Help me fix this bug on my game!

I am building a game in Construct 2 and I added police cars and I want them to chase the red car. I used the PATHFINDING behavior and it works quite fine, but then there's a problem: the cars are overlapping each other even though I've set them as solid objects and added them as obstacles. How can I solve this problem?

Have you cheked the collisions of the objects? Could be a problem with that. You can find a tutorial of how to set them here:

You could also try the physics behaviour, that works a little better (At least for me). Here's how to do it:

Hope that helped.

Preventing pathfinding objects from overlapping is a popular topic, but there is no easy and universal solution. You can search the forum and tutorials, there are many posts about this. I have two examples, but they are quite complex and may not suit your game very well. (you can open them in free version of C3)
