[resolved]Why can't the bullets using the trigger once condition be destroyed?

A round white bullet is shot out and overlaps with the enemy, but it is not destroyed, but passes through the enemy. Removing the trigger once can destroy it. This is why.

If you are utilizing a translator then it has made your question confusing.

I can’t read the language in the picture so here is your events written with “white”, “grey” and “variable” instead of your language.

For each white
Trigger once
White overlaps grey
— white: destroy
— white: set variable to 1
— white overlaps grey
— — white: destroy

Every tick
White: variable=1
— white: destroy

white: overlaps grey
— destroy white

Instead of all that, wouldn’t this work to destroy white when it overlaps grey?

white: overlaps grey
— destroy white

But maybe you’re trying to do something else. Also, I should point out that you probably never want to use “trigger once” in a loop.

You can see that I used multiple instances of "white: destroy" because none of them worked. White passed through, and I need white to be destroyed when it touches grey.I found my mistake, and now I will remove the trigger once.
