Methods

draw(verts, conf1, conf2)

Draw a set of vertices with this program, with optional configuration. Configurations passed here do not overwrite the cached object. This method is accessed when Palette.Manager#draw is called.
Parameters:
Name Type Argument Description
verts Float32Array Vertex list to pass to the GPU.
conf1 object <optional>
 A set of attributes to pass down to the fragment shader.
conf2 object <optional>
 A set of attributes to pass down to the vertex shader.

restoreDefaultConfig(mode)

Restore a program's object config for either shader or both.
Parameters:
Name Type Description
mode int The identifier for which config object to revert. Supports Palette.Program.VS_MODE, Palette.Program.FS_MODE, Palette.Program.BOTH_MODE.
Source:

setConfig(mode, conf)

Set a program's object config for either shader or both with a given config object. Object properties not in the supplied object will not overwrite the program state.
Parameters:
Name Type Description
mode int The identifier for which config object to set. Supports Palette.Program.VS_MODE, Palette.Program.FS_MODE, Palette.Program.BOTH_MODE.
conf object The config object to inject into the program state.
Source:

setDrawMode(mode)
