Multiple objects interfering with each other

[Orogenesis]

Hello! Sorry for the somewhat obscure post title - I wasn't exactly sure what to say!
Question for Clickteam Forums.mfa
All details are included within this CF2.5 file, but I'll write some basic information for search purposes.

When my object is by itself, it performs the intended actions with ease. However, when I make multiple copies of the same object, they all begin to act ... oddly. Now, when using cloned versions of the original, they all work perfectly. I've tried both behaviours and the event editor.

If any of you could help me, I would be very grateful.

PS - Sorry if the answer is obvious, or if it's an issue with my coding.

EDIT: Like a fool, I forgot to upload the version that has my documentation of how the car works, so I'll copy/paste here:
Hi there! Let me walk you through what's happening here.

The car is trying to get to the circle in an organic fashion. To do this, the car is always given target coordinates. In this car, the car always has mouse as the target. (LN 2).

If the place that the car is headed to (I'll explain this variable shortly) is different from the target (read: always), a momentum is applied. These variables are mom_x and mom_y, and they are basically vectors. (LNs 19-22)

The place that the car is currently headed to is called the predictive coordinates. It is the current coordinates of the car added to the momentum that we calculated above. This is pred_x and pred_y. (LN 3)

The final step in the process is applying the momentum to the car. It will be the current position added to the momentum. (LN 4)

LNs 24-29 are all things that make the car bounce off the sides.

Hi

You could use a for each loop to address this.
See the changes I have made in the updated mfa.

This works for behaviors as well.

Wow, that's interesting! Thank you for the reply, and have a great day.
