Raycast; Old Unity Forum post from 2007 with "Simple Way Code": Slippery Slopes. However, I'm running into an embarrassing issue: the ball keeps rotating, so I'm not able to find a constant downward ray to use for finding the ground. Problem with raycasting, checking for ground doesn't work. In the code above, we check whether the left mouse button has been clicked. I have a ‘working’ code that sets the items position to the camera’s position but i’d like it to be a few units in front of the camera as to avoid clipping issues and only aligning with the y rotation value instead of the x value and the y value. Unity - Ground Checker: Get angle of sloped ground underneath the player - GroundChecker. Assigning this boolean was the most mystifying for me when I was learning how to work the Unity Animator. 0 physics is not 100% compatible with Unity 4.

If you have played strategy games like Command and Conquer or Red Alert, you can drag your mouse and select the units within that square you just made with your mouse. Something we need to know for changing states is whether or not the player is standing on the ground. Check if raycast 1 && 2 is true then object is fully visible, if 1=false, 2= true - object is crouching and so on). The core concept behind the Character Controller is that it provides basic collider responses without any physics. slopeLimit: The character controllers slope limit in degrees. //checks if there is anything under character if is set grounded to. This is a static class, so you just need to call it from another class. The RaycastHit passed as reference will have the ray origin's transform. Sign in Sign up Instantly share code, notes, and snippets. This function returns a RaycastHit object with a reference to the collider that is hit by the ray (the collider property of the result will be NULL if nothing was hit). Then, to get the correct normal (and to avoid the interpolation between two normals that you mention here) of the "correct" ground, I think you should raycast so that its contact point is equal to the other one given by the spherecast (or maybe spherecast with a radius of like 0.
