77297fd60d Text Tool and Pan Tool
Two new tools added to the Level Editor:

* Pan Tool: left-click to scroll the level around safely.
* Text Tool: write text onto your level.

Features of the Text Tool:

* Can choose from the game's built-in fonts, size and enter the message
  you want to write.
* The mouse cursor previews the text when hovered over the level.
* Click to "stamp" the text onto your level. The currently selected
  color swatch will be used to color the text in.
* Adds two new fonts: Azulian.ttf and Rive.ttf that can be selected in
  the Text Tool.

Some implementation notes:

* Added package native/engine_sdl.go that handles the lower-level
  SDL2_TTF logic to rasterize the text into a black&white image.
* WASM not supported yet (if the game even still built for WASM);
  native/engine_wasm.go stubs out the TextToImage() call with a "not
  supported" error just in case.

Other changes:

* New Toolbar icons: they are 24x24 instead of 32x32 to make more room
  for more tools.
* The toolbar now shows two buttons per row for a more densely packed
  layout. For very narrow screen widths (< 600px) the default Vertical
  Toolbar layout will use one-button-per-row to not eat too much screen
  real estate.
* In the Horizontal Toolbars layout there are 2 buttons per column.

eb24858830 Brush Pattern Textures
Palette swatches gain a new property: Pattern.

Patterns are grayscale textures that the swatch color will sample
against when drawing pixels to the level, by taking the world coordinate
modulo a value inside the texture.

A few algorithms were tried (Screen, Overlay), this branch lands on one
that tries to cast the color from grayscale which comes out rather dark;
to get a patterned color to look black while still seeing the pattern,
the color needs to be as bright as #777 to get the effect.

17b18b8c0a Better Ellipse Drawing Algorithm 2019-07-16 18:27:00 -07:00
0c6c77a423 Lemon-shaped Ellipse Tool (WIP)
* Add initial Ellipse Tool to the Editor Mode. Currently there's
  something wrong with the algorithm and the ellipses have a sort of
  'lemon shape' to them.
* Refactor the IterLine/IterLine2 functions to be more consistent.
  IterLine used to be the raw algorithm that took a bunch of coordinate
  numbers and IterLine2 took two render.Point's and was the main one
  used throughout the app. Now, IterLine takes the two Points and the
  raw algorithm function removed.

cc1e441232 Eraser Tool, Brush Sizes
* Implement Brush Sizes for drawtool.Stroke and add a UI to the tools panel
  to control the brush size.
  * Brush sizes: 1, 2, 4, 8, 16, 24, 32, 48, 64
* Add the Eraser Tool to editor mode. It uses a default brush size of 16
  and a max size of 32 due to some performance issues.
* The Undo/Redo system now remembers the original color of pixels when
  you change them, so that Undo will set them back how they were instead
  of deleting the pixel entirely. Due to performance issues, this only
  happens when your Brush Size is 0 (drawing single-pixel shapes).
* UI: Add an IntVariable option to ui.Label to bind showing the value of
  an int reference.

Aforementioned performance issues:

* When we try to remember whole rects of pixels for drawing thick
  shapes, it requires a ton of scanning for each step of the shape. Even
  de-duplicating pixel checks, tons of extra reads are constantly
  checked.
* The Eraser is the only tool that absolutely needs to be able to
  remember wiped pixels AND have large brush sizes. The performance
  sucks and lags a bit if you erase a lot all at once, but it's a
  trade-off for now.
* So pixels aren't remembered when drawing lines in your level with
  thick brushes, so the Undo action will simply delete your pixels and not
  reset them. Only the Eraser can bring back pixels.

a504658055 Centralized Tick Counter, Fix Actor Dragging Bug
* The game's tick counter was moved from Doodle.ticks to shmem.Tick
  where it is more easily available from every corner of the code.
* Fix a bug in the Level Editor where dragging an already-existing actor
  from one part of your map to another, would cause it to lose all its
  data (especially its UUID), breaking links to other doodads. Now the
  existing Actor catches a ride on the drag object to be reinserted
  later.
* Animate the Link Line visualizers between actors. They now animate a
  blinking color between magenta and grey-ish.

5a1ec156ca Editor Mode: Line Tool and Rectangle Tool
* Add support for the LineTool and RectTool while in the EditorMode to
  easily draw straight lines and rectangle outlines.
* Key bindings were added to toggle tools in lieu of a proper UI to
  select the tool from a toolbar.
  * "F" for Pencil (Freehand) Tool (since "P" is for "Playtest")
  * "L" for Line Tool
  * "R" for Rectangle Tool

c8620f871e Drawing Strokes and Undo/Redo Functionality
* Add new pkg/drawtool with utilities to abstract away drawing actions
  into Strokes and track undo/redo History for them.
* The freehand Pencil tool in EditorMode has been refactored to create a
  Stroke of Shape=Freehand and queue up its world pixels there instead
  of directly modifying the level chunker in real time. When the mouse
  button is released, the freehand Stroke is committed to the level
  chunker and added to the UndoHistory.
* UndoHistory is (temporarily) stored with the level.Level so it can
  survive trips to PlayScene and back, but is not stored as JSON on
  disk.
* Ctrl-Z and Ctrl-Y in EditorMode for undo and redo, respectively.
