Welcome to Lacerate! you have a demo of how that works. The demo is you making the grey cat move. Here, you have to drag the "red flag pressed?" block. and then move -2 step and change costume in order. press the red flag and tada! you made the cat move now! however, the cat cant go out of bounds, because we dont wanna see any mistakes happening here!
this is a ripoff of scratch c2a lmao
