MarchingSquaresMesh

Description

This class converts a 2d array of bits into a shape using an algorithm called March Squares.

ArrayMesh arrayMesh:
The internal Godot class that actually draws the mesh onto the screen.

BitMap bitmap:
Reference to the bits that is read by the algorithm to draw the shape.

int MapWidth:
Width of the bitmap. Automatically set based on canvas size. DO NOT MODIFY.

int MapHeight:
Height of the bitmap. Automatically set based on canvas size. DO NOT MODIFY.

float OffsetScale:
Gets or sets the amount of jitter to randomize the positions of each mesh cell point.

BitMap[] brushes:
Gets the list of BitMaps representing the different brush sizes.

BitMap previousBitmap:
Gets the previous bitmap just before the latest edit. Used to record Undo history.

Dictionary Save ( ):
Save the mesh into the save file format and return it as a Dictionary.

void Load ( Dictionary data ):
Load a saved mesh data. Used by a saved map file to load existing meshes.

void Resize ( int x, int y, int w, int h ):
Called automatically when the canvas is resized. DO NOT CALL DIRECTLY. FOR REFERENCE ONLY.

void OnDrawingEnd ( ):
Finishes the mesh for drawing and records an Undo history.

void CreateNewBitmap ( ):
Create or replace the bitmap with an empty one of the right size.

void SetBitmap ( BitMap bitmap ):
Replace the bitmap with a specific one and updates the visuals. WARNING: THE SIZE MUST MATCH!

void Clear ( ):
Delete the visuals and data of this mesh without destroying the instance.

void SetCircle ( Vector2 position, int size, bool value ):
Draws a circle at the position onto the mesh if value is true or erase if false.
