void dbSetAlphaMappingOn(int object, int percentage);

This command will alter the transparency, or alpha value, of the selected object. A value of 0 will make an object completely transparent while a value of 100 will make the object completely visible.

An example of how to use alpha mapping:

$ dbSetAlphaMappingOn(1, 50); // This will make object one have an alpha value of 50% $
