Raycast Issue Unity Engine Unity Discussions I am having an issue with raycasting where the raycast doesn’t hit at one point in time but on the next iteration it hits. basically, i have two cards next to one another on a playing board, they are at a fixed position. The raycast query ends when there are no more hits and or the results buffer is full. the order of the results is undefined. when a full buffer is returned it is not guaranteed that the results are the closest hits and the length of the buffer is returned. if a null buffer is passed in, no results are returned and no errors or exceptions are.
Raycast Hit Point Issue Unity Engine Unity Discussions About ray cast unity ray cast unity is a professional grade raycasting module built specifically for unity 3d projects. it provides access to advanced hit scan techniques, layer masked queries, distance limited detection, and debug visualization. ray cast unity offers engine level functionality while remaining lightweight and easy to integrate, making it an essential tool for both indie. In this article, we will try to provide a comprehensive guide on mastering unity’s raycast function for game development. we will cover everything from the basics of creating and controlling rays to advanced techniques like limiting raycast by max distance or layer masks. I’m having some raycasting issues with a course i’m following. the script i’m working with (which was provided by the instructor) is supposed to return one of three layers depending on the mouse position. however, it only returns the first layer (walkable) and never returns the second layer (enemy). the third layer is just a default value. Oh, i thought the collider in the picture was on layer 10. i just did realize a problem: the yellow raycast may be working, but it’s at the exact same coordinates as the blue one. only one ray will be visible because of that. try putting a debug.log in each one so you know if they are called.

It’s been some time now i’m noticing very, very odd behaviour from physics.raycast and physics.linecast. i am using the 3 parameters raycast, where parameter 1 is the origin, parameter 2 the direction and parameter 3 the maxdistance. Put all of your players and enemies on layer 2 (ignore raycast) and run tests to see if nothing is between them… also, raise your target hit point if your characters origin points are at their feet. this will prevent things on the ground from blocking your view. i assume you are writing this in c#. so i made the variables match that format. Since you mentioned that you need to play for a long time before the issue reproduces, my initial gut feeling tells me that something’s drifting away and is no longer where you expect it to be. I thought maybe it was using the sphere or player colliders to activate the raycast hit, but if i add them to a layer mask and add that mask to the ignore when processing the raycast, it just doesn’t work at all.
