I know that "for each" runs with every tick, thats why I created this thread in the first place. I looked for forum entries on how to use instances with events, but I could only find examples with "for each". Is there a specific tutorial that covers instances in events that you can point me to?
Not just "for each", but all non-triggered top-level events run on every tick. (Triggered events have a green arrow in the icon, for example "On collision")
And in most situations you don't need to use "for each" loop, you can pick instances without it.
Like I said, check out the official templates. This is the best way to learn Construct.
