Reproduction Steps:
Quite hard to reproduce this issue freely on your own but can be experienced at [Car Dealership Tycoon] (đ SEASON 1! Car Dealership Tycoon - Roblox) for PC users. Works fine in studio, mobile, tablet and console. Most likely caused by collision groups, objects that should collide with each other doesnât collide.
Expected Behavior:
When you enter the car, wheels should collide with the ground and you should be able to drive around normally. At the moment it works fine for mobile, tablet and console. Doesnât work on PC.
Actual Behavior:
When you are playing on PC and spawn a car, collisions are not working properly, wheels clips through the ground which results in that the car is not drivable. Both the car and the ground are connected to Collision Groups and should collide with each other. In studio game it works flawless.
We have exactly the same problem in Hot Wheels Racing. Started around 14 days ago. The workaround was to make the collision group collidable with itself.
Yes this is the same issue! Works when I made the wheels collision group collidable with itself. Can drive the car normally but instead other features in game wont work such as races where you should not collide with other cars and players
So in the game there are collision groups for wheels and bodies for cars. Wheels should not collide with each other but the ground, important for cases like races or when you have collisions settings disabled in game when you donât want to collide with other cars in the game. As @GMaxZet said it works if I make the group collidable with itself, but again it disables some other important features in the game.
Would you be able to make a simplified repro case using the Beta Feature setting (Accelerated Collision Pipeline) in Studio? Self-Collision shouldnât affect how the group collides with other groups.
I have the same game Car Dealership Tycoon published to a private place by mine, the collisions have started to work as they should again (didnât work for an hour ago). Still doesnât work properly in the official game.
Hard to do a simple repro then when it has started to work on most places but not the official game.
Man itâs not clear for my side either Very confusing. Something must have changed at least in the last hours. I swear I tested many different ways this morning. And I didnât change anything at that time when it stopped working in game.
I donât think itâs Beta Feature, because I can still see that this is enabled via Microprofiler. If you see the stepMidPhase scope in physics, then the feature is enabled.
We had that issue in live game and we did not publish like for 10 days, so we were pretty sure that it was roblox issue, as we saw release notes for the update n. 475:
Very confusing. Something must have changed at least in the last hours. I swear I tested many different ways this morning. And I didnât change anything at that time when it stopped working in game.
