For Loop: Action every 4 steps?

I searched the forums but couldn't figure this out. I might be using the wrong terms. I have a ForX=1to32 and ForY=1to32 event loop, and instead of performing the action every 1 step, I want it to perform the action every 4th step. Something like this:...

Step1: X=0, Y=0 - Do action

Step2: X=4, Y=4 - Do Action

Step3: X=8, Y=8 - Do Action

Etc...

Thanks

store the number 4 in a variable, and multiply that in the steps

You can use a modulo operation. For example if your event loop is 1 to 32, use from 0 to 31 and add a sub condition "if loopindex % 4 = 0". You won't need an extra variable in this case, saving on memory and processing!
