gpu_get_colourwriteenable

This function can be used to retrieve the current colour write-enable values. The function returns a 4 element 1D array with the following elements in it which will be either true (enabled) or false (disabled). By default all colour writing is set to true:

• [0] = Red channel enabled/disabled
• [1] = Green channel enabled/disabled
• [2] = Blue channel enabled/disabled
• [3] = Alpha channel enabled/disabled

Syntax:

gpu_get_colorwriteenable();

Returns:

Array (4 elements only; see above for details)

Example:

var cw = gpu_get_colorwriteenable();
cw[3] = false;
gpu_set_colorwriteenable(cw);

The above code gets the current colour write values and then sets the alpha component to false.
