I have tried using Raycast and OnMouseEnter and OnMouseOver to check if player is over a button made from a 3dCube in Unity. The Ray always corresponds to a point in the view, so the Camera class provides the ScreenPointToRay and Oof, getting an accurate ray from the mouse in the scene view is annoyingly difficult, because the raw mouse position (Event. For perspective cameras, viewport points off center will have a different direction than transform. I need to identify the position that the camera needs to move to so I In the section Understanding the View Frustum, it was explained that any point in the camera A component which creates an image of a particular viewpoint in your scene. Returns a ray going from camera through a screen point. mousePosition) is relative to the entire Unity application window, not relative to the scene viewport. When what you need is to use the game space coordinates, which is done by using Camera. However, I am planning for the camera to be able to look around; however, the bullet is traveling to the center of the screen instead of going straight out of the barrel. It means that Camera. C# Unity Raycast problems, camera not responding. width, Screen. point` which hold the actual hit position in world space coordinates. See clip: My code: using System. It’s a parameter that uses the ‘out’ keyword. Even thpugh the raycast is hitting So in 4. Could I get some help? Also, lookAt is the player capsule’s transform, and camTransform is the camera’s transform (obviously.

If he llok too high at the object, then prefab instantiate too high than centre of the screen. RaycastAll() but it does not Physics. I do it by code: RaycastHit hit; Ray ray=Camera. You can indeed set the maximum distance, and then all of your selections can be handled as RaycastHits. I want to draw the ray, but it is not drawing until the ray intersects with another object, then it draws the ray from camera to player. 5f, 0)); Hi Rajesh, I’m a total Unity noob (I just downloaded it 2 days ago) but I believe this maybe what you are looking for: function Update() { var x = Screen. I know how to fire a raycast from a spawn point forwards, but am currently unable to shoot rays to the centre of the screen, where my crosshair is.

I don’t really know how to do it, I’ve seen such things as ScreenToWorldPoint(), but I don’t know how to use it (Why a Vector3 for input ? If we are talking about a screen, shouldn’t it be a Vector2 ?) I’m thinking about Raycast and stuff but I’m really I am using RaycastHit with the MainCamera which works correctly and hitting targets with the Oculus VR etc. ScreenToWorldPoint was returning the center of the screen area of the Camera and to it work right. It working but looks like ray dont casting right because sometimes not hit sometimes h&hellip; I have canvas which have rendered texture as image from camera. The reason why you do the first raycast instead of just shooting the projectile from the gun towards the center of the screen is that doing it that way will cause it to be inaccurate and produce different results at different ranges due to the bullet traveling on an angle instead of straight towards the crosshair the user is aiming. Here’s the sniper rifle script I want to change: var GunCamera : Camera; var shotSound: AudioClip; // Making an RTS-style camera and having some issues with rotation.

I attach a script with this code to the controller gameobject, but it does not appear to shoot the raycast forward. Raycast (cam. Finally I assumed that ray should pass through object centre at the closest point if ray vector would be exactly the same size as camera-object vector. The code should send a debug message when I look at something that has a tag. I am facing this issue from a few days, I want to shoot a Raycast inside the UI reticle but I can’t get it working as it should, changing the screen aspect ratio or the reticle size is enough to make the bullet go outside the reticle, for example setting I want to make a raycast projecting from the camera, but with a radius (CapsuleCast), so that there’s a lot of leeway for looking and still triggering what I need to trigger.
