What I think you are looking for is a circle that emanates from the user and that does not move over a distance. Use Unity to build high-quality 3D and 2D games, deploy them across mobile, desktop, VR/AR. ![]() Now, to get the direction the cue ball travels, we just need to rotate the previous vector 90 degrees. Unity is the ultimate game development platform. Debug.DrawRay(transform.position, -Vector2.up RayLong, Color.white). Any Collider2D making contact with the circle can be detected and reported. We just need to invert it by doing: -1 hit.normal. But basically, if you just want to click the mouse directly on an object and have the raycast hit it, this should work: Code (csharp): RaycastHit2D hit Physics2D.Raycast( ( Input. A 'CircleCast' is conceptually like dragging a circle shape through the Scene in a particular direction. Anyways, im new to Unit圓D, CSharp, and the Forum too. Use Unity to build high-quality 3D and 2D games, deploy them across mobile, desktop, VR/AR, consoles or the. This means that in unity, we can use the hit.normal to get the direction of travel for the ball we hit. A Unity ID allows you to buy and/or subscribe to Unity products and services. A good analogy to describe it is that CircleCastAll is throwing a frisbee of a certain radius over a distance and then returning all object that this frisbee hits. Unity is the ultimate game development platform. All results are sorted by ascending distance order. I think you are misunderstanding how CircleCastAll works. You should check if the RaycastHit2D collider is null to know if you actually hit something or not. Overloads of this method that use contactFilter can filter the results by the options available in ContactFilter2D. A Unity ID allows you to buy and/or subscribe to Unity products and services. The layerMask can be used to detect objects selectively only on certain layers (this allows you to apply the detection only to enemy characters, for example). Note that you will always get zero results if you pass an empty array. ![]() See Also: Physics2D.Raycast, Ray2D class. The RaycastHit2D class is used by Physics2D.Raycast and other functions to return information about the objects detected by raycasts. Con el motor de Unity usted puede crear juegos 2D y 3D, aplicaciones y experiencias. The RaycastHit2D class is used by Physics2D.Raycast and other functions to return information about the objects detected by raycasts. El Manual de Unity le ayudará a aprender y usar el motor de Unity. The significance of this is that no memory is allocated for the results and so garbage collection performance is improved. A raycast is used to detect objects that lie along the path of a ray and is conceptually like firing a laser beam into the Scene and observing which objects are hit by it. A raycast2d is continuously shot downward, and when it collides with an object on the enemy layer it registers the collision and returns its value. I have a movement script attached to my player object. The integer return value is the number of objects that intersect the circle (possibly zero) but the results array will not be resized if it doesn't contain enough elements to report all the results. As the title suggests I would like to destroy the game object that my raycast hits. It also returns the centroid where the circle would be positioned for it to contact the collider at that point. This function returns an array of RaycastHit2D object(s) with a reference to the collider that is hit by the circle (the collider property of the result will be NULL if nothing was hit) and contains both the point and normal of the contact where the circle would touch the collider. Store a reference of it in your script and use that. ![]() ANOTHER EXTREMELY IMPORTANT THING 1: Do not use Camera.main in Update (), as it uses a GetComponet call, which can cause perormance decreases. A "CircleCast" is conceptually like dragging a circle shape through the Scene in a particular direction. You just input the mouse position and then use this new ray to do the raycast. It turns out that the distance value that i expect should be: Code (CSharp): float expectedDistance raycastHit.distance - 2 skin and the raycastHit.point should be: Code (CSharp): Vector2 expectedPoint raycastHit.point + raycastHit.normal skin This smells like a skin width to me.
