Webb4 okt. 2024 · Unity Physics.Raycast with LayerMask does not detect object on layer. Used bitshifting, tried inverting layer, still nothing works. novice to intermediate Unity developer here. I've been hitting a pretty significant roadblock the past ~2 days concerning the raycast detection of objects with specific layers. 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:

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 … Webb7 maj 2024 · 実は最初に挙げたPhysics.Raycast(Physics2D.Raycast)には引数がいくつかあり、その中に引数でLayerMaskを設定できます。これは、入力したint値のレイヤーマスクのみを判別するというものです。 pitcher trevor bauer

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

Webb6 mars 2015 · 1 Answer Sorted by: 7 The casting between int and LayerMask can be a bit confusing. When you call LayerMask.NameToLayer ("Enemy"), you get the layer index. Let's assume that "Enemy" is layer 7, so that call would return 7. So far, so good, but a layer index is not the same as the bitwise layer mask that is used by the raycast function. 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. pitcher tyler andersonWebb6 jan. 2024 · A layer MASK is a 32-bit bitfield that says which of these you want to ignore.

"WebbFor example, if you want to perform a RayCast against GameObjects on layer 9, if you pass 9 into the Physics.Raycast call as the layerMask, Unity actually performs the ray cast against GameObjects on layers 3 and 0. This is because the binary representation of 9 is 00001001 and if you interpret this as a mask, the 1s are in the place of layers ... " - Physics.raycast layermask

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). Webb7 nov. 2024 · To do this, you want to have your LayerMask floorLayers so that only floors are checked, then in your Raycast: Physics.Raycast (transform.position, dirDown, out hit, 10f, ~floorLayers.value) If you do this, any hit will be a floor hit, and you don't need to do any bit math below.
