WebIn the following screen caps, the blue line is the vector returned by RaycastHit.normal: The white line is the original direction of the sphere; the red line is the ray from the centre of the sphere to the collision point, for which the normal supposedly is computed. The documentation says the normal is "the normal of the surface of WebNov 8, 2024 · Ok, so if you are aware of the Vector3 you are passing as a parameter you are giving to Camera.ViewportToRay(), that is a normalized space (I think that it is a Moebius Space).You are giving to z a 0 parameter, so the ray would reach the start of the viewport, you may play with values between 0.1-1.0 for z, to deal with distance.

To make a ray cast ignore a GameObject, you can assign it to the Ignore Raycast layer, or pass a LayerMask to the ray cast API call. If you don’t pass a LayerMask to the ray cast API call, Unity uses Physics.DefaultRaycastLayers which matches every layer ...
Webbool raycast =Physics.Raycast(ray.origin,ray.direction,out RaycastHit hitInfo,float maxDistance,int layerMask); 这里有五个参数，第一个是发射起点，第二个是发射方向，第三个是发射距离，第四个是射线碰撞信息，第五个是发射图层，只检测指定图层，而忽略其他图层，最后返回值bool是是否击中某个碰撞体或者触发器。 WebApr 11, 2024 · The first ray is fired from the player's-eye view, to find out what's under the crosshair, so you know what worldspace point to aim at. The closer that point is, the more you need to angle your shot inward to hit it. The second ray is fired from the tool/weapon muzzle, toward the hit from the first ray.
WebThe ray is a geometric creature: a line starting at some point (the origin) and following indefinitely in some direction. Physics.Raycast is a test that verifies whether some collider is hit by the ray specified, and RaycastHit is a structure that Raycast fills with info about the first object hit by the ray - it has invalid values if nothing hit, thus only read it when …
