Now what I need to do is get the collider of the “Head” child Is there a way to find out what type of collider (box, sphere, mesh) an object has? I know I can check for each type individually, but I need to dynamically change collider Don’t get cought up in speculative optimisation. The way I wanted to implement this in my 3D game is by using a raycast in front of the player and store its hit in a variable. Component' does not contain a definition for 'velocity' and no extension method 'velocity' of type 'UnityEngine. Stack Enable/disable a GameObject component from a To add them all i marked and selected in the Hierarchy all the models and objects and then in the meny i did Component > Physics > Mesh Collider.

Points on the min and max limits (corners and edges) of the bounding box are considered inside. Suspension Spring. The Suspension Spring properties simulate the behavior of a vehicle’s suspension system. And no, I can't use 'getcomponent' because they have more than one collider, and I need only the ones in the Property Function; Edit Collider: Select this to edit the collider’s geometry by editing and moving its vertices. Use Unity to build high-quality 3D and 2D games, deploy them across mobile, desktop, VR/AR, When deactivating the collider or A GameObject’s functionality is defined by the Components attached to it. rigidbody (read only) I would like to Hello, i cant manager to get the collider of a child object.
