Making of a rollable total field

In today’s video tutorial I will show you a typical usage of Number controls to create some bonus field with a rollable total (with a pretty straightforward LUA code).

Sorry, the LUA code is blurred in the video for the most part, here is the code:

function onInit()
	addSourceWithOp("mod1", "+");  
	addSourceWithOp("mod2", "+");  
	addSourceWithOp("mod3", "-");  

	super.onInit();
end

Note that mod3 is declared as subtracting instead of adding to the total.
