Yeah that’s getting there.
If I was doing this I’d probably do something like so.
Depending on what your exact goal is you’d need to modify this of course but this should get you started.
You don’t really need to enable input every time you press the button, only when you need it to be active.
In this case I set it on begin play, but maybe if you’re making a base building game you might want it only when you have the building selected.
Also doing something like scaling up by 1 exactly might not be best, you could make it relative by multiplying or maybe just do smaller intervals.
