I'm using PolygonColliders because sprites can be highly irregular, so they add a lot of realism to collisions. In my testing, the framerate drops to ~30 (from 60, because VSync) when around 50 sprites are on screen. I don't expect to have this many enemies on screen, but I'd like to make ...

WebApr 10, 2024 · 7 4. From what I observed you're only considering face normals for collision. This causes the incorrect contact point generation when the sphere is near the edges or vertices of the polygon since it only considers the face-to-sphere contact. You should also consider edge-to-sphere and vertex-to-sphere contacts. – Brixxon Tulabing. WebAside from the braces problem (for some reason the Unity docs don't use braces in their examples), it was that BOTH the object colliding AND the object being collided with need …
WebApr 27, 2024 · Steps to detect collision in Unity 3D. The game object on which collision detection will be triggered should be having Rigid Body and Collider components. For this demo, we will attach Rigid body component to the player game object. Box collider is already available to primitive Cube objects. Make sure Is Kinematic check box is unchecked. WebJun 7, 2024 · You can check for a collision within the collider by using the void OnCollisionStay2D(Collision2D collision) method for whichever object that you want to …
WebTo check for collision, we’re going to use a separate boolean variable. This will be inside our function later, so if this gets confusing, jump to the full example at the bottom. boolean … WebJun 30, 2012 · Since unity doesn't raycast on inside sides, you have to flip the faces in your 3d authoring tool. Then you have to raycast in the opposite direction to make up for the other side. (I haven't figured out how to get the count of hits from the raycast yet. But I am using a cube right now, which only has 2 perpendicular faces, so it works) Unity ...
WebThe component MeshRenderer fetches the entire SpatialMesh and not the polygon where the collisions occured. Even in that case, the SpatialMesh does not change its colour upon collision. Although if I insert a kinematic game object (KGO) then its colour is being changed when my movable game object (MGO). My script follows.
