This sets a named parameter for a shader element
| Important Note: It's enough to set the texture only once if it's a render target |
Syntax
bool dxSetShaderValue ( element theShader, string parameterName, mixed value )
OOP Syntax Help! I don't understand this!
- Method: shader:setValue(...)
Required Arguments
- theShader: The shader element whose parameter is to be changed
- parameterName: The name of parameter
- value: The value to set, which can be a texture, a bool, a number or a list of numbers(max 16 floats(numbers))
Returns
Returns true if the shader element's parameter was successfully changed, false otherwise.
Example
myShader = dxCreateShader( "hello.fx" ) myTexture = dxCreateTexture( "man.png" ) dxSetShaderValue( myShader, "texture0", myTexture ) -- Set a texture dxSetShaderValue( myShader, "bShowThing", true ) -- Set a bool dxSetShaderValue( myShader, "speed", 2.4 ) -- Set a float dxSetShaderValue( myShader, "positionOfCheese", 100, 200, 300 ) -- Set a list of numbers, with max 16 numbers. Btw, this is a float: 3.4. This can be used to fill an array in HLSL.
