some information on the Lua api

Input functions

• InputIsKeyDown(Keyboardkey Key) returns true if a key is down
• InputGetAxis(string axis) returns a -1 to 1 float for a axis

Memory

• Allocate(int size) returns a new byte array

File IO

• ReadBinaryFile(string file) returns the contents of a file as a byte array
• SaveBinaryFile(string file, byte[] data) saves binary data to a file
• BinaryReader(string file) returns a new binary reader

Vector2

the Vector2 class is a simple 2D vector with X and Y values

Vector2 functions

• Vec2(float x, float y) returns a new Vector2
• Vec2GetAngle(Vector2 me, Vector2 target) returns the angle between two points
• Vec2GetDirection(Vector2 me, Vector2 target) returns the direction between two points
• Vec2GetLength(Vector2 x) returns the length of a Vector2
• Vec2Distance(Vector2 me, Vector2 target) returns the distance between two points

Color

the Color class has 4 values:

• float r
• float g
• float b
• float a

these use 0 to 1 values like in GLSL shaders, however you can use Color255 to convert byte colors to float colors

ex: Color255(255,255,255,255) returns 1,1,1,1

color functions

• Color(float r, float g, float b, float a) creates a new GLSL style color(0 - 1)
• Color255(byte r, byte g, byte b, byte a) creates a new color from normal rgb values (0-255)
• ColorMix(Color a, Color b, float weight) returns a and b mixed together by weight
