This sets a named parameter for a shader element.

Important

It's enough to set the texture only once if it's a render target.

OOP Syntax Help! I don't understand this!

• Method:shader:setValue(...)

Syntax

​bool dxSetShaderValue ( ​element theShader, ​string parameterName, ​mixed value )

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 int/float or a list of numbers (max 16 floats(numbers) ).

Returns

• bool: result

Returns true if the shader element's parameter was successfully changed, false otherwise.

Code Examples

Example 1 Example 2 (OOP)

client

local myShader = dxCreateShader("hello.fx")
local 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.
