How do I know how big my duty-free allowance is when returning to the USA as a citizen? My idea is that there is a plane which is more of a border at top of the screen and if a game object has no more space to fall and it collides with something while it is in that border, the game ends. with hit.transform. Then you can create a script on your object that sends out values using the OnTriggerEnter () {}, OnTriggerStay () {} and OnTriggerExit () {} functions. What happens if you connect the same phase AC (from a generator) to both sides of an electrical panel? Unity: Detect which collider component of gameobject is colliding with something. @s4vi0r has a good solution if youre using box colliders, but a lot of us are asking about colliders in general, which would include spheres, capsules, and mesh colliders. You can selectively ignore collisions by only checking for certain kinds; in duct's post, isTouching() can check for a specific object, or isTouchingLayers() checks for a specific layer. (Lets say you wanted to use compareTag on the transforms). Thx! Then, create a "cube" primitive and add it as a child of this empty object. The first being your Border Collider, the second being the "Play Space" collider. Check out unity SweepTest() and Collider.bounds for specific syntax and what not.

See this solution if youre looking to do checks on concave MeshColliders, but its certainly overkill otherwise so pick the solution that works for you. Your question is bit clumsy, What your are trying to do, tell it clearly. This works fine, until I enable the collider component of Object A while it is inside of the collider of Object B. The solution bellow should account for these in a generic manner. So you only want to react on collision events when the object is within a given zone and react them otherwise? Bounds.Contains will always return False. Just iterate through some set or subset of points (the eight corner points of the box collider, or six iterations of "closest point to target" using the six directions on a sphere), then check all of them for "is inside of collider bounds". you could create a Sphere in a 3D modelling software and invert the normals so that they face inside the sphere.

Powered by Discourse, best viewed with JavaScript enabled, Test if point is in Collider/Trigger - Unity Answers. Then the player can go back to a non-trigger on that frame, and the other object can use OnTriggerExit to know when the player is no longer inside of it Add a BoxCollider which surrounds the whole of the object you are testing for and check its bounds min and max are contained within the BoxCollider its entering this may not suit for complex mesh objects but you may be able to get away with it and its cheap. One workaround might be to use 4 really small colliders placed around the object and dont fire unless all 4 enter.
