Description
Sets or removes post processing effects for this sprite.
Sprite:setEffectStack(effectStack,mode)
The effect stack is an array of tables, each one describing a post processing stage. Each table can have the following fields:
- buffer: a RenderTarget that will hold the input of this post processing stage
- shader: a Shader that will be used to draw the buffer above onto the next stage, or on screen optional
- transform: a Matrix to transform the input buffer before processing optional
- postTransform: a Matrix to transform the final stage output before displaying optional
- textures: an array of TextureBase to be used by the shader. By default the buffer is used. optional
- clear: a boolean indicating to clear the buffer before rendering. True by default for the first effect of the stack, false otherwise. optional
- autoBuffer: a boolean to tell Gideros to resize the buffer to match the Sprite size automatically. False by default. optional
- autoTransform: a Matrix used in computing the Sprite size when autoBuffer is enabled. optional
Parameters
effectStack: (table) a table describing the post processing phases to be applied
mode: (number) one of the Sprite.EFFECT_MODE_* constants optional
Example
local blur = Shader.new("Vertex", "fBlur", 0,
{
{name="vMatrix", type=Shader.CMATRIX, sys=Shader.SYS_WVP, vertex=true},
{name="fColor", type=Shader.CFLOAT4, sys=Shader.SYS_COLOR, vertex=false},
{name="fTexture", type=Shader.CTEXTURE, vertex=false},
{name="fDir", type=Shader.CFLOAT2, vertex=false},
{name="fResolution", type=Shader.CFLOAT2, vertex=false},
},
{
{name="vVertex", type=Shader.DFLOAT, mult=3, slot=0, offset=0},
{name="vColor", type=Shader.DUBYTE, mult=4, slot=1, offset=0},
{name="vTexCoord", type=Shader.DFLOAT, mult=2, slot=2, offset=0},
}
