Making a button is easy. Step 1: make a blueprint. Step 2: draw a button shadow on the blueprint and add another layer as the button then add another frame as the button being pressed down. Step 3:add a variable by pressing something like a settings.. Step 4: add script
Script: while this is pressed
Script: modify current frame to 1
Script: modify variable (your first variable in step 3) to 1 (or just create a new actor if it's spawning)or something
Add another Script
Script:when a touch ends on this
Script:modify current frame to 1
See? easy right????
