How can I create puplic variables/edit collision boxes

make a control if Object Referenz has
the value 1 or 1-9. If value=1 it
should create a rectangle and if the
value =2 the bp creates a oder object

This can be done with what I showed, except the bool needs to be an int, that’s all.

If you want to make something like Minecraft, it’s time to switch to C++, as blueprint will not be fast enough. It’s good for learning with though.
