Spawning on frame generates unwanted multiple obj.

Hi all.

Here's the situation:

Sprite A on a frame number 4 is to spawn sprite B with bullet behavior.

How to avoid constantly creating sprite B when frame number 4 lasts?

I need only one sprite B spawned on frame.

Thanks in advance.

If you add a condition "Trigger once while true" (you can find it in the System object, under the "special conditions" category) to the event that checks the sprite A current Frame, the event will only trigger once every time A hits his 4th frame.

Here is a tutorial by Ashley on the subject, and other advance event features.

Thank You very much, Guizmus. I think this will do the trick.
