# Built-in Doodads
|
|
|
|
Sketchy Maze comes with several built-in doodads that you can use in your
|
|
levels. You may also [create your own](custom-doodads/index.md) custom doodads
|
|
and program them to do whatever you want!
|
|
|
|
Doodads are available in the Level Editor by clicking on the
|
|
<img src="images/sprites/actor-tool.png" width="16" height="16"> **Doodad Tool**
|
|
and then dragging a doodad onto your level. See the [Doodad Tool](custom-levels/index.md#doodad-tool)
|
|
for more information.
|
|
|
|
**See also:** [Linked Doodads](linked-doodads.md) for how doodads interact when
|
|
linked together in your levels.

## Objects
|
|
|
|
### Start Flag
|
|
|
|
|
|
|
|
The **Start Flag** sets the player spawn point in your level. There should be
|
|
only one start flag per level.
|
|
|
|
Multiple Start Flags in one level is considered to be an error; a warning is
|
|
flashed on-screen and the player will spawn at the "first" start flag it found.
|
|
|
|
A level without a Start Flag will spawn the player at the 0,0 coordinate at
|
|
the top-left corner of the level, and flash an error about the missing Start
|
|
Flag.
|
|
|
|
If the Start Flag is [linked](linked-doodads.md#start-flag) to another doodad
|
|
in your level, then that doodad will be used for the player character. For example,
|
|
linking a Start Flag to a Thief will use the Thief as the player character
|
|
for that level instead of the default character, [Boy](#boy).
|
|
|
|
### Checkpoint Flag
|
|
|
|
|
|
|
|
The **Checkpoint Flag** records the player's position in the level each time
|
|
he reaches a checkpoint. Should they die during the level, the option to
|
|
"Retry from checkpoint" will teleport the player back to that location and
|
|
continue gameplay without resetting the level -- so you keep any keys you
|
|
have, unlocked doors remain unlocked, etc.
|
|
|
|
The default checkpoint location is at the Start Flag, and crossing Checkpoint
|
|
Flags updates it to the last flag touched. When a second checkpoint is touched,
|
|
the previous checkpoint flags are reset and the player's spawn point is the
|
|
checkpoint they most recently touched.
|
|
|
|
### Exit Flag
|
|
|
|
|
|
|
|
The **Exit Flag** sets a goal point for the level. The player must touch this
|
|
flag to win the level.
|
|
|
|
### Anvil
|
|
|
|
|
|
|
|
The **Anvil** is a "harmless" object that becomes dangerous when it is falling.
|
|
|
|
It has no collision and is affected by gravity; when falling, it is dangerous
|
|
to any **mobile** doodad that it encounters, including the player character.
|
|
Being hit by it will fail the level with "Watch out for falling anvils!" and
|
|
you can retry from your last checkpoint. It destroys other mobile doodads that
|
|
it lands on, removing them from the level.
|
|
|
|
If it receives a **power** signal (from a [linked](linked-doodads.md#buttons)
|
|
Button or Switch), the Anvil will reset to its original location on the level,
|
|
making "reset buttons" possible for puzzle levels.
|
|
|
|
### Box
|
|
|
|
|
|
|
|
The **Box** is a pushable object. If the player or another mobile doodad touches
|
|
the box from the side, the box will move at a fixed speed. It can be pushed up
|
|
and down slopes and it is affected by gravity.
|
|
|
|
The box is taller than [Boy](#boy) and so can make a useful platform to jump on top of
|
|
to reach a higher ledge.
|
|
|
|
Boxes can be pushed by enemies too, but it gets dicey with multiple enemies
|
|
pushing simultaneously. Boxes can be stacked on top of each other, but sometimes
|
|
Boy will get "stuck" standing on top of the pile. If this happens, use the
|
|
[cheat code](hacking.md#cheat-codes) `ghost mode` to get yourself unstuck.
|
|
|
|
**New in v0.8.0:**
|
|
If it receives a **power** signal (from a [linked](linked-doodads.md#buttons)
|
|
Button or Switch), the Anvil will reset to its original location on the level,
|
|
making "reset buttons" possible for puzzle levels.
|

# Creatures
|
|
|
|
### Boy
|
|
|
|
|
|
|
|
**Boy** is the player character.
|
|
|
|
If he touches a "fire" pixel, he dies! You get a message like "Watch out for fire!"
|
|
and it doesn't even have to say "fire" - it'll use the color's name.
|
|
|
|
If he touches water he'll turn blue. Swimming physics aren't hooked up yet!
|
|
|
|
### Red Bird
|
|
|
|
|
|
|
|
The **Bird** is a simple creature which flies left and right across your level,
|
|
changing direction when it encounters an obstacle.
|
|
|
|
The bird has solid collision on its top side, so the player can ride on it
|
|
across the level. It's very slippery, though!
|
|
|
|
In the future, the bird will dive-bomb the player character in a diagonal
|
|
trajectory when it sees a shot it can take. This will harm the player if the
|
|
bird hits. If the bird hits the player, or misses and touches the ground, it
|
|
will fly back up to its original altitude and continue its A.I. program of
|
|
flying back and forth and searching for the player. It will also be easier to
|
|
ride more reliably.
|
|
|
|
Currently, however, the bird is harmless and does not dive bomb the player.
|
|
|
|
**New in v0.8.0:** the Bird no longer can pick up items such as keys, unless
|
|
controlled by the player character.
|
|
|
|
### Azulians
|
|
|
|
|
|
|
|
The **Red Azulian** was the first test mobile character, and the
|
|
**Blue Azulian** was originally the player character in very early builds of
|
|
the game.
|
|
|
|
The Azulians' A.I., when placed in your level, is that they walk right and
|
|
left across the ground, changing directions when hitting an obstacle. They
|
|
can pick up keys, unlock doors, and interact with buttons and switches that
|
|
they walk onto - basically all the capabilities as the player character.
|
|
The blue Azulian walks half as fast as the red one.
|
|
|
|
You can play as them in your custom levels by linking a Start Flag to
|
|
the Azulian.
|
|
|
|
### Thief
|
|
|
|
|
|
|
|
The **Thief** is a mobile character which can steal items from other doodads,
|
|
including the player character.
|
|
|
|
The Thief's A.I. is to walk right and left, she can pick up items, unlock doors,
|
|
and activate most devices that it walks onto. When she encounters another
|
|
doodad (including the player), the Thief will **steal** any items they are
|
|
carrying:
|
|
|
|
* For items which have no quantity, such as the Blue Key, the Thief will only
|
|
steal it if she does not already have one, letting the player keep the
|
|
key.
|
|
* Items with quantity are always stolen: the Thief will steal all your small
|
|
keys.
|
|
* The A.I. Thief does **not** steal from other A.I. Thieves.
|
|
|
|
The player can play **as** the Thief by using the Link Tool and connecting
|
|
the Start Flag to a Thief. When controlled by the player character, the Thief
|
|
has special abilities compared to most other characters:
|
|
|
|
* You can steal items from other characters. When you contact another character
|
|
such as the Azulians, if they are holding any items, you'll automatically
|
|
steal them in the same way the Thief usually steals from you.
|
|
* The player character is immune to Thieves which will not steal from Thieves.
|
|
* The player character _can_, though, pilfer items that the other Thieves have
|
|
collected.
|

## Doors & Trapdoors
|
|
|
|
### Colored Locked Doors & Keys
|
|
|
|
 
|
|
|
|
There are four pairs of **Colored Locked Doors and Keys** you can use on your level.
|
|
|
|
Colored doors are locked and behave as a solid wall until the player or another
|
|
mobile doodad "picks up" the Key of the same color. The doors may then be
|
|
permanently unlocked if the player walks into them while holding the key.
|
|
|
|
The **Colored Keys** are not consumed when used; with one key the player can
|
|
unlock many doors of the same color unless they lose the key. Currently there is
|
|
no method to lose keys except for the "drop all items" [cheat code](hacking.md#cheat-codes).
|
|
|
|
A locked door has a golden padlock over its sprite; after being unlocked, the
|
|
padlock is missing even while the door is closed. Should the player lose the keys
|
|
later, previously opened doors will remain unlocked but the player will need to
|
|
find another key to open more doors.
|
|
|
|
   
|
|
|
|
Each key/door pair also has a distinct shape for color-impaired players:
|
|
|
|
* **Red Key** (triangle)
|
|
* **Green Key** (cross)
|
|
* **Yellow Key** (star)
|
|
* **Blue Key** (diamond)
|
|
|
|
### Small Key Doors
|
|
|
|
 
|
|
|
|
**Small Key Doors** are doors which consume the **Small Key** when unlocked. The
|
|
player or other mobile doodad may carry several Small Keys and they can only
|
|
unlock as many Small Key Doors as the number of keys they hold.
|
|
|
|
The Small Key Door is permanently unlocked after unlocking it once. A golden
|
|
padlock appears on the door when it's locked, which disappears after unlocking.
|
|
|
|
### Warp Doors
|
|
|
|
|
|
|
|
The **Warp Door** allows the player character to fast travel between two remote
|
|
locations within the same level. The door is brown in color with a yellow "W"
|
|
symbol.
|
|
|
|
To connect the doors together, drag two doors into your level and then use the
|
|
**Link Tool** to connect them. During gameplay, walk the player character to one
|
|
of the doors and press the Space Key to open it. The door will swing open and
|
|
shut and the player character exits from the other door.
|
|
|
|
If a Warp Door is not linked to another door, a message will display indicating
|
|
that the door is "locked" and it can not be entered by the player.
|
|
|
|
**See also:** the [Blue & Orange Warp Doors](#blue-orange-warp-doors) tied to the
|
|
[State Blocks](#state-blocks).
|
|
|
|
### Trapdoors
|
|
|
|
|
|
|
|
A **Trapdoor** is a one-way passage. If the player or other mobile doodad touches
|
|
the door from the "correct" side, the door will swing open. After the mobile
|
|
doodad has passed, the door will swing shut again.
|
|
|
|
When the door is shut, you can not open it from the "wrong" side and it behaves
|
|
as a solid wall. If the door is open you may run in from the wrong side.
|
|
|
|
Trapdoors come in four variants: downward-facing (default), rightward, leftward
|
|
and upwards.
|
|
|
|
### Electric Door
|
|
|
|
|
|
|
|
The sci-fi **Electric Door** can only be opened when it receives a "power" signal
|
|
from a linked button or switch. See [Linked Doodads](custom-levels/index.md#link-tool).
|
|
|
|
When the door receives a "power: on" signal it will open and allow passage to
|
|
the player or other mobile doodads. When it receives a "power: off" signal it
|
|
will close.
|
|
|
|
### Electric Trapdoor
|
|
|
|
|
|
|
|
The **Electric Trapdoor** requires a power source to open it.
|
|
|
|
If it receives a power signal from a linked Button or Switch, it will open.
|
|
When it loses power, it will close. Switches will always toggle its state
|
|
regardless of "power" status.
|
|
|
|
### Crumbly Floor
|
|
|
|
|
|
|
|
The **Crumbly Floor** behaves as a solid ceiling when hit from below, and a
|
|
solid floor when walked on from above, but watch out! The floor will shake
|
|
and collapse after a moment beneath your feet.
|
|
|
|
The floor will respawn after a while and forbids passage from the underside
|
|
of the doodad.
|
|
|
|
---
|
|
|
|
## Gizmos
|
|
|
|
The gizmo doodads work best when **Linked** to other doodads in your level. For
|
|
example, a Button linked to an Electric Door will cause the door to open whenever
|
|
the button is pressed.
|
|
|
|
**See also:** [Link Tool](custom-levels/index.md#link-tool)
|
|
|
|
### Buttons
|
|
|
|
 
|
|
|
|
**Buttons** will emit a `power: on` signal to all doodads that they are
|
|
[linked to](custom-levels/index.md#link-tool) when the button is pressed by the
|
|
player or another mobile doodad.
|
|
|
|
When the button stops being pressed, it will emit a `power: off` signal to
|
|
all connected doodads, which will generally close electric doors.
|
|
|
|
Buttons come in two varieties which are cosmetic only:
|
|
|
|
* **Button:** a button with a grey arrow that pops back up when pressed.
|
|
* **Button Type B:** a variation without the grey arrow but behaves the same.
|
|
|
|
### Sticky Button
|
|
|
|
|
|
|
|
The **Sticky Button** is a variant of the Button but with a red arrow on its side.
|
|
|
|
When the Sticky Button is pressed, it will emit a `power: on` signal and it will
|
|
**remain pressed** forever -- unless the button itself receives a `power: on`
|
|
signal from another linked doodad, then it will pop back up and can be pressed
|
|
again.
|
|
|
|
### Switches
|
|
|
|
 
|
|
|
|
**Switches** will emit a `power: on` signal to any [linked](custom-levels/index.md#link-tool)
|
|
doodads when touched by the player or other mobile doodad, and then a `power: off`
|
|
signal when touched again.
|
|
|
|
Switches come in a few different styles (all cosmetic in nature and behave the
|
|
same way):
|
|
|
|
* On/Off "background" wall switch that faces the screen.
|
|
* Side-profile switches to attach to the side of a wall (left and right).
|
|
* Side-profile floor switch.
|
|
|

|
## Boolean State Doodads
|
|
|
|
The **Boolean State Doodads** are a series of doodads which have a mutually
|
|
exclusive state from one another, with their state toggled by the "ON/OFF"
|
|
State Button.
|
|
|
|
### State Button
|
|
|
|
 
|
|
|
|
The **State Button** globally toggles the boolean state for all doodads in the
|
|
level which are sensitive to the state.
|
|
|
|
The player character must jump into the ON/OFF block from below and hit it with
|
|
their head. From above, the ON/OFF block acts like a solid floor that the player
|
|
or other mobile doodads can stand on top of.
|
|
|
|
In the future it will be possible to bonk the ON/OFF block from the sides or
|
|
top with enough force, but currently only hitting it from the bottom will flip
|
|
its state.
|
|
|
|
* When the button is **OFF**, all **blue** state doodads are active. This is the default state.
|
|
* When the button is **ON**, all **orange** state doodads are active.
|
|
|
|
### State Blocks
|
|
|
|
 
|
|
|
|
 
|
|
|
|
**State Blocks** are blue and orange squares that keep opposite state from one
|
|
another. In one state the block is solid, in another it is passable.
|
|
|
|
The ON/OFF block will toggle all state blocks on the level to their opposite
|
|
setting whenever it's touched by the player or other mobile doodad.
|
|
|
|
### Blue & Orange Warp Doors
|
|
|
|
 
|
|
|
|
 
|
|
|
|
The **Blue & Orange Warp Doors** are variants of the [Warp Door](#warp-doors) that
|
|
are sensitive to the ON/OFF State Blocks. These doors can only be opened while the
|
|
door is in the "ON" (active) state -- when "OFF" (drawn as a hollow dotted outline)
|
|
the door can not be opened by the player. However, a player may still **exit** from
|
|
a de-activated door.
|
|
|
|
The **Blue Warp Door** is active at the same time as the **Blue State Blocks**,
|
|
and vice versa for the **Orange Warp Door.**
|
|
|
|

|
|
|
|
## Technical Doodads
|
|
|
|
"Technical" doodads tend to turn invisible during gameplay and have some useful
|
|
interactions for certain situations.
|
|
|
|
### Goal Region
|
|
|
|
|
|
|
|
This doodad acts like an invisible Exit Flag, winning the level if touched by
|
|
a player character.
|
|
|
|
### Checkpoint Region
|
|
|
|
|
|
|
|
This doodad acts like an invisible Checkpoint Flag, recording the player's
|
|
progress in a level.
|
|
|
|
### Fire Region
|
|
|
|
|
|
|
|
This doodad will trigger the fail condition if touched by the player.
|
|
|
|
### Power Source
|
|
|
|
|
|
|
|
On level start, this doodad emits a `power(true)` signal to all linked doodads.
|
|
Connect it to an Electric Door, for example, and the door will open immediately
|
|
when the level begins.
|
|
|
|
### Stall Player
|
|
|
|
|
|
|
|
This doodad will freeze the player character for 250ms, one time. It is useful
|
|
if you need to slow down the player to get some timing in your level to work
|
|
out.
|
|
|
|
If this doodad receives power from a linked button, it will reset the trap,
|
|
and will freeze the player again for 250ms should they make contact with the
|
|
doodad again. |
