I have 3 game objects that moves by rigidbody.velocity. But if there is an external object that moves towards the game object (by dragging), the external object can push away the game objects.
What I want is the game object cannot be pushed away or at least very hard to push away.
do not quite get your question but if you want
A.to your object be ‘unpushable’? one option could be just to activate IsTrigger toggle in object collider
B.your object to avoid pushing others, check oncollision event and check for collision’s object name or tag, if it is something you do not want to collide with, then change one’s property to trigger while they are collisioning.
hope one of those helps. good luck and happy coding
