How use Immediate number in AGAL

For example, I want to output red color in fragment shader.

HLSL:

return float4(1,0,0,1);

asm:

def c0, 1, 0, 0, 1
mov oC0, r0

How to implement this in AGAL?

Solution 
  • mov oc, fc0

    you have to pass in the red constant via:

    context.setProgramConstantsFromVector(Context3DProgramType.FRAGMENT, 0, Vector.<Number>([1.0, 0.0, 0.0, 1.0]));

    unfortunately, you can't define a constant in agal.
