Weird overlapp with moving BP

Hello,

Something strange happening, and I can’t explain why…

I have a 33 vehicles blueprints already placed in the world:

This vehicles moves thanks to “Set Throttle Input”:

This vehicles can detect overlapps with other vehicles:

→ My problem, is that sometimes vehicles detect overlap with other vehicles who have moved from their initial positions.

When I hit pause during game, after a “ghost” collision in order to check “player collision”.
There is no collision shown.

Before “Play”:

After I hit “Play”:

The problem does not always occur, sometimes overlapp does not happen.
Only difference between cars are visual mesh.

Please tell me if it needs more explanation or details.
Thanks a lot for help !

wdym, by this: vehicles detect overlap with other vehicles who have moved from their initial positions.

When I hit pause during game, after a “ghost” collision to check “player collision”.
There is no collision shown. Could you explain your problem more?, I don’t Understand the terms “ghost collision,” and “Player collison” in specific. I don’t understand your problem and question in general.
Regards.

Thanks for your time!

I’m going to try to explain better, let’s imagine a case where you have:

  • A level with a road
  • 2 vehicles BP on this road, lets say “Veh1” and “Veh2”
  • When I hit play on the level, the vehicles moves on the road
  • The 2 vehicles can overlapp each others

→ My problem is that sometimes, when for exemple “VEH2” reach “VEH1” initial position (by initial I mean the position before I hit play), it detect an overlapp with “VEH2” even if “VEH2” are in another location, and not in his initial position anymore.

I hope that this explanation is more clear. :slight_smile:

In Your vehicle blueprints, how do you move your vehicle? can you show me that code?

Hello, thank you for your answer, sorry for late I wasn’t at home.

Of course, in order to move the vehicle I set him a Throttle Input with the “Vehicle Movement Component”, from the default “Wheeled Vehicle Pawn”.
