The nop instruction does no operation, it does nothing.
The nop syntax looks like this:
nop;
Example code:
texture T_Image; // <- Main texture
technique tech_main
{
pass P0
{
Texture[0] = <T_Image>;
PixelShader = asm
{
ps.1.1; // <- Pixel shader version
def c0, 0.5, 0.3, 0.1, 0.0; // <- Declaration of a constant, we treat it as a color (r, g, b, a)
tex t0; // <- Load the T_Image texture
nop; // <- Do nothing.
add r0, c0, t0; // <- Assign the addition of colors from the texture and from the constant to the final result: result.rgba = const.rgba + texture.rgba
mov r0.a, t0.a;
};
}
}
This example requires the following in the .XML file:
- Flag <dx8>yes</dx8>
(More information about .XML files can be found here)
