This raycast is to check for any collider to be hit, but so far there's only two objects for it to hit in the scene which is my ground and table. Once you have begun to utilize the features of the raycast in Unity, the various results could be endless. In this video we take a look at the two most dominant methods for scripting gun functionality inside of Unity. A raycast is conceptually like a laser beam that is fired from a point in space along a particular direction. Raycast takes a direction in world space. Why can't you just do a raycast in the direction of the player (from your enemy)? A raycast just returns the first object hit if any (and you can give it a range too), so if it hits something, just check if it's the player. I had this problem in one of my last game: ” Color Slide“. The velocity change when the direction o. The last thing we'll add to the Raycast function is the Layer mask. Raycasting is one of those topics that everyone seems to struggle with at first, so here is a tutorial covering everything you need to know about raycasting in Unity.
