Game problem. Can't find the solution

alextro could you just explain again what you mean by your previous comment where you said

"Sprite1 is overlap Sprite2, Trigger once >> Destroy Sprite1

Put 'Trigger once' after 'overlap'."?

Thank you

It just how the condition should arranged in that order within same block condition, with 'Trigger once' put at very bottom. With this setup the action will execute once, each time the condition met.

Say that you want to add value to a variable each time sprite1 (and it's instances) hit sprite2. So if the sprite1 overlap sprite2 at one time, the action will trigger. Another time they overlap again, the action will trigger again.

It will be different if you put 'Trigger once' at very top order. Try it by yourself

alextro thank you, i will give it a try and let you know

alextro so just to clarify how should I write it out?

Thank you

For further assistance you can just PM me if you can't show you current work here. Because what you might think about with my own though could be different. Couples of years ago I might just like you, uncertain about how to write the code down to achieve specific result.
