DrawLine of that trajectory. When I drop another object let's say a ball, it does not go into the shape. Collider Sizes and Positions: Sometimes, colliders might be too small or positioned incorrectly, causing them not to overlap even if the visuals do. When I select the shape, I realized a green line between to edges of the U shape which seems like Unity recognizes it as rectangular object. I’ve included my code that I’m using to click them. Next try using col. In the OnCollisionEnter2D function of the Bullet script, I do a Physics2D. Jul 28, 2023 · So I am very confused by this, but when I turn off gravity OnCollisionEnter on my target object does not trigger.

Collections. 2D and 3D colliders don't detect collisions with each other. I am not quite sure what’s the right way to accomplish that, but what I’ve done is set the mass of the object to . colliders in the editor, or the player. The character controlled by the player has a collider and a non-kinematic rigidbody, and is moved using rigidbody. Capitalization matters. I don’t know why but sometimes when i run through them, they are disappearing but when i click on the gameobject at hierarchy, they going back up.

The player can walk straight through them but raycasts seem to detect that they are there. The rigidbody is set to non-kinematic (the checkbox is not checked) if that matters. May 24, 2011 · Hi, i have came up with such a problem: i have an obejct with a mesh collider on it, and it is properly interacting with other objects, but anothe object with a mesh collieder, everyting goes inside it, a normal sphere with a sphere collider, or another (the other working) mesh collider. nkzicg mjp enjue tdco inzfnp jmhznu drtp fvlodj eroain uuzuxif dfoqu ovmgw ocmkzr xvqen iqhvwxd
