Weird overlapp with moving BP

[Krystoh]

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.

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.

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”.
