Hi everyone, i'am pretty new here, but i hope to get help. I try to describe my problem shortly. i have two buildings on a plane(lets say GroundBuildings) . And one object on the mouseposition(MouseBuilding). all the Buildings have colliders. With a mouseclick i can release the MouseBuilding. This is not possible when the collider of the MouseBuilding enters the colliders of the GroundBuildings. Thats what i want and it works well. I work here with a normal boolean variable. And now my problem. When the building on my mouseposition (MouseBuilding) leaves one of the GroundBuildings the boolean gets true. But when i now enter the second GroundBuilding , there is a short moment the boolean stays true even though the colliders hit each other and with fast mouse click i can release the MouseBuilding in the second Groundbuilding. I think the problem is, the Collisiondetection is to slow. I use OnCollisionEnter and OnCollisionExit. I tried to use OnCollisionStay to remain the boolean false. But same problem. And i have the same problem with OnTriggerEnter and OnTriggerExit. Also tried the collisiondetection Continous and Continous Dynamic etc. Problem is sill there. Would be awesome if someone can help me.
