Collisions and object spawns at lower time scales issue

Hi all! I have an object with the platform behaviour on it, I'm using "simulate pressing left/right" to move it (no manual player input). When this object collides with a wall object that has the solid behaviour, the wall spawns a single sprite.

The collision type I am using is "on collision with" - not "is overlapping". This works as expected with the wall object spawning a single sprite on collision, however if I drop the timescale down to say 0.3 instead of spawning 1 object on the collision, it creates many, over and over again.

I'm just wondering why this is, and if there is any way, at these low timescales to ensure that a collision is only checked once. I know that 0.3 is a very low timescale to use, but am experimenting with slow motion effects and wanting to ensure the game presents consistently. Thanks for any insight!

I'm guessing Platform behavior knocks the character a fraction of a pixel back when it collides with the wall. Maybe with a low timescale it's enough to register a new collision on the next tick.

Try checking if "Platform Has Wall on left/right" in the events where you simulate platform movement. So that if the character is already near a wall it will not move.

Thanks for this idea, only issue is though that the sprite with the platform behaviour needs to patrol back and forth between walls after the collision and checking for a wall will stop this once it has collided. I can live without the slow mo effect but it's making me worry about the reliability of the collisions as they are quite fundamental to progression.
