So, your code would end up like this: We get the vector difference between the player and the enemy ( the vector between the player and enemy ), then we normalise so the vector is of unity length and only describes a direction. Using that and an origin, Ray can figure out that it must shoot from origin towards direction. Rated by 85,000+ customers. Use MathJax to format equations.

We want to make sure our raycasts cast from outside our player collider about 0.2f to the right for our right detection, 0.2f to the left, 0.2f above our player and 0.2f below our player. In Unity, Raycast uses mathematical variables like position, range etc to make this possible. Physics.Raycast can takes up-to five parameters which are: 1. A Raycast is basically a ray that is drawn from the player to the ground in this case. This shows us that ray takes 2 parameters; an origin( the place the ray is being cast from ), and a direction. Detect if the player is landed on top of a box with rigidbody. Found insideSo, well done: at this stage we can cast rays and detect the object in front of the player. So the next step for us is to create and fire a weapon, and detect, using the ray cast, whether and where the bullet has hit a target.

Pixel size depends on your screen resolution. Physics.Raycast(ray, out hit, LayerMask.GetMask("Ground")) This is a common mistake as LayerMask.GetMask returns an int which will be implicitly cast into a float and thrown into maxDistance instead of layerMask. A collider doesn’t need to be exactly the same shape as the object’s mesh - a rough approximation is often more efficient and indistinguishable in gameplay. Think of each unique Scene file as a unique level. Information is then returned about the object and the point that was hit in a RaycastHit object.
