Max speed - Decrement

On a collision to a wall with the Car Behavior, I wanted to lower the Max Speed on every collision.

I tried On Collision between Car and Wall:

Sprite[Car].MaxSpeed = Sprite[Car].MaxSpeed - 50

Any help on how to make the car go slower with each collision?

Well your method is working ok. Just remember to use "On Bounce" and set wall attribute to "Solid"

I have bounce to stop and wall to sold but i am not getting a decremented slowdown after each hit

Try the Car Behavior's "On Bounce" condition instead of On Collision.

On Collision checks for overlap between two sprites. It's basically the same as this:

+ Car is overlapping Wall
+ Trigger Once
    -> Do stuff

Since the car is bouncing away from the wall before it's overlapping then you will never get On Collision to trigger.

On Collision has been modified for other behaviors in the past though.  For instance, you can use On Collision with Physics objects to detect collision even though they don't overlap either.  You might want to make a feature request to have Car recognize On Collision in the same way, if it's important to you somehow.  Otherwise just use On Bounce.

OK I got this to work with:

Car[Car].MaxSpeed -50

The problem is I was using stop first (because I do not like the large bounce back), and with the car stopped touching the wall It subtracted the -50 untill I was unable to move

I with bounce did not push you so far back. Is there a way to edit the amount of bounce?
