This function is not supported in earlier versions. |
Sends one or more colors to a special (extern / uniform) vec3 or vec4 variable inside the shader. The color components must be in the range of [0, 1]. The colors are gamma-corrected if global gamma-correction is enabled.
Extern variables must be marked using the extern keyword, e.g.
extern vec4 Color;
The corresponding sendColor call would be
shader:sendColor("Color", {r, g, b, a})
Extern variables can be accessed in both the Vertex and Pixel stages of a shader, as long as the variable is declared in each.
In versions prior to 11.0, color component values were within the range of 0 to 255 instead of 0 to 1.
Function
Synopsis
Shader:sendColor( name, color, ... )
Arguments
string name
- The name of the color extern variable to send to in the shader.
table color
- A table with red, green, blue, and optional alpha color components in the range of [0, 1] to send to the extern as a vector.
table ...
- Additional colors to send in case the extern is an array. All colors need to be of the same size (e.g. only vec3's).
Returns
Nothing.
