This command will set the value of an FX effect matrix constant.

SET EFFECT CONSTANT MATRIX Effect Number, Constant String, Matrix Number

Effect Number

Integer
This value is an integer number such as 1.

Constant String

String
This value is a string value encased in speech marks.

Matrix Number

Integer
Specify a matrix number between 1 and 65535.

This command does not return a value.

An FX effect constant is one of many internal variables of the effect which control the effect in real-time based on what the FX does. Some constants are automatically provided to the FX system effect such as world and camera positions, time and other critical data. Often, FX files will contain extra constants to create a variety of results and these constants can be altered in real-time by this command. Use the PERFORM CHECKLIST FOR EFFECT VALUES to get the names of all the constants you can alter.

make object sphere 1,100

load effect "goodshader.fx",1,0

set object effect 1,1

r=make matrix4(1)

r=make vector4(2)

set identity matrix4 1

set vector4 2,0,10,5,0

set effect constant matrix 1,"TransformMatrix",1

set effect constant vector 1,"LightPosition",2

end
