Raycast in order to detect an object which works fine, now i want to make the raycast detect two layers, in order to execute seperate tasks. 10f1. Assigning a game object to Unity’s ‘Ignore Raycast Layer’ will prevent the game object from getting in the way of the ray and in turn receiving the OnMouseDown event. Infinity, int layerMask = DefaultRaycastLayers); You are passing a layermask as the distance parameter I’m making a lock on system, so to detect where the mouse is pointing I used a raycast. I found this tutorial online which provided the code: #pragma strict var LaserOrigin: Hi, When a player dies in my game I use: hitTransform. I also have a Terrain, I want my raycast on the script “Ore” to only work when clicking the ore (Not the Terrain). which is layer 0. The distance of the raycast is specified in the 3rd parameter. Physics. Where there is a 0, it will ignore collisions. This can be used in the layermask field of Physics. var myLayerMask : LayerMask; and use myLayerMask. I have only one object assigned to that layer. So in the beginning of your code that fires when the raycast hits, you Hello community, i’m currently using an Physics. We also add in two new variables, which are tempLaser and stopRaycast. Courses. For example, a large laser beam, with a wide radius, that might Basically the layer mask is just an integer. learn tutorials so I’m becoming more confident.

Although we cannot accept all submissions, we do read each suggested change from our users and will make updates where applicable. There are many use cases of raycast like we can create bullet shooting with it, it can get any information of the gameobject and check if “A Layer mask that is used to selectively ignore Colliders when casting a ray. how can i make that it only penetrates the glass and stop at whatever layer is behind it. Currently, the raycast hey guys, so i’ve been trying to make a raycast bullet script, which a single ray could hit different game objects in different layers. Close. Keep in mind that your raycast is infinite. Raycast. Raycast(initialPosition,RayVector,Distance,AND ONLY DETECT THIS LAYER); How do I do that ?! I see this bit shifting operations with 1<<20 and stuff , but does 1<<20 mean “only 20” or “nothing below 20” ? How can I , by script define a Raycast that detects only 2 layers for There’s a very neat way of doing this. So i don’t think i can use the ignore layer option.

I’m lost. Hello, I’m needing to use a ray (ScreenPointToRay) and output the hitinfo, as well as use a layer mask. What you think is being passed as a layer mask is really being interpreted as the distance you want to raycast. Any object that isn’t included in the layermask will behave exactly the same as the Ignore Raycast layer. Since you bit-shifted to get the layermask i would assume that it would only detect the default layer, and unity documentation says it should only collide with that layer. Like the title,i want to ignore raycast for some other layers,I know there is a layer called ignore raycast but i want to ignore more other layers,like my own “player” layer,no need to dectect raycast ,how to ignore more than 2 layers?? Thanks for any hints!! Unity Engine. using UnityEngine; using System. My understanding is that if you pass a layermask with a Raycast, the Raycast will ignore that specific layer, and register hits for all others, correct? And then if I want to reverse this - have collisions register for just this layer and ignore all others, I can just flip the The raycast call you are making is actually: Physics.
