Hi Metro
Thanks for your reply. The actions that you did seem not enough to what I need.
I have a variable that changes with player's frequent inputs.
And I need to change the variable to its floor or ceiling value.
For example, when the value is 1.5 and the player presses up, it needs to become 2 , if the player presses down, 1.
And the value can be anything > 0.
So any other ideas?
There should be an action to customize math function for the variables....
