Webb1 apr. 2015 · So my solution was: Physics.Raycast () needs 4 veriables in order to use a Layermask. So i had to add a distance to the ray. i.e. Physics.Raycast (ray, out hit,mathf.infinity,rayMask) that got the layermask working Although it was the Inverse of what i thought, the ray hit only what was on the mask. So i added. Webb9 aug. 2024 · It's much easier to understand and deal with layer masks if you abstract it. As an example, if you want to get a mask for specific layers: LayerMask mask = LayerUtility.Only ("Player", "Friends"); Or if you want to exclude specific layers: LayerMask mask = LayerUtility.AllBut ("Enemies", "Obstacles"); Here is the main utility class:

How can I have a raycast ignore a layer completely? - Unity

WebbTo ignore a layer, Check this link, scroll down to Casting Rays Selectively : // JavaScript example. function Update () { // Bit shift the index of the layer (8) to get a bit mask var layerMask = 1 << 8; // This would cast rays only against colliders in layer 8. // But instead we want to collide against everything except layer 8. WebbI found an important thing about layermasking, layermasking seems to fail on even number layers. the time this happenes is when I bitshift int layerMask = gameObject.layer << gameObject.layer; then I use layerMask = ~layerMask; and use that in the layerMask slot of the raycast function, when tested, I found that the ray would ignore all odd numbered … s\u0026h good eats cafe slidell https://jpsolutionstx.com

This is unrelated to URP. That's part of the rendering system, while raycasts are handled by the physics system, and it's the same physics system no matter what renderer you use. When you give a layer mask to a raycast, you are asking it to consider colliders only on the layers enabled in the mask. Webb6 jan. 2024 · A layer MASK is a 32-bit bitfield that says which of these you want to ignore.

Checking if the Raycast hit, hits a layer from the LayerMask?

Webbbool 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。 Webb10 nov. 2024 · Edit 2: I debugged a bit more and found out that I am an idiot and that the LayerMask you specify in Physics.Raycast is actually what layer it ignores. However after correcting my mistakes the slime trail is still able to make the player float in mid-air, although only for the first jump from the ground, it can't go infinitely up like before.

Webb13 sep. 2024 · At first I thought that the problem was how the layers were called, because I created a LayerMask combining 2 layers using the bitwise OR operator, but then I tried to play around with all the layers (hence why there is walkableMask = ~walkableMask; now). The result was always a false output for Physics.Raycast (ray, out hit, 100, walkableMask).
