Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Ai actors with physics, stuck in place. Only if multiple Ai actors in world.

Hi not sure if this is a bug or my doing.

I created a tank with a USimpleWheeledVehicle movement component and PhysxVehicle.VehicleWheel. I use SetDriveTorque() for forward/back movement and AddActorLocalRotation() (with teleport physics enabled) to rotate.

In my game Ai tanks are to move towards the player (this works with one Ai tank). However with two or more Ai tanks only one can move and the rest are stuck in place and jitter around as they try and move. This only happens after a tank rotates. If I destroy the moving tank another Ai tank then starts moving.

After looking for answers I tried using StopMovementImmediately(), this allows all tanks to move freely but very slow. So would like a better solution.

Anyone know why this is happening or how to fix it?
