Trying to get enimes to randomly spawn...

So you want to make random spawn of enemies in platform game, yep?
"I've tried the hot collision, where you overlap an active and an enemy will spawn but that's not what I want."
So how it should looks like?

An easy way might be to have an invisible active move across the top of the screen. You could then have that active shoot another invisible active, at random intervals, downwards. When that active collides with the background, create the enemy.

Something like:

- Every random(300)+50
=create enemy at 0,0
=set x position of enemy to random(Frame Width)

Yeah, PBarwick's solution will work.

So it supports variable (grid-based) heights, I expanded on it a little. This should give you some ideas to work with:

Caesar's solution will do well too, and support slopes; but to have precise spawning on those slopes (default clickteam movements tend to be buggy and stick in obstacles) you'd need to give your spawners a custom fast-loop movement, which is a bit more in-depth.

Here's a tweak on my original example that uses fastloops to hitscan the spawner objects to the top of any obstacle, even slopes.

It's a bit more performance expensive but it shouldn't be a problem unless you're spawning large multiples of enemies at a time.
