UNITY RAYCAST TUTORIAL CODE

Also if I increase the obstacle size or collider size I can eventually block the left side. If this total path distance is shorter than current path distance set this as targetįor some reason the raycasts trigger on the right side of the obstacle but not the left. If(CanSeeDestination(transform.localPosition, surroundingPoints) & CanSeeDestination(surroundingPoints, ))įloat distanceFromEnemyToTarget = Vector3.Distance(transform.position, surroundingPoints) įloat distanceFromTargetToPlayer = Vector3.Distance(surroundingPoints, ) įloat totalDistance = distanceFromEnemyToTarget + distanceFromTargetToPlayer If enemy can reach this surrounding point and this surrounding point has an unobstructed path to the target Loop through array of surrounding vectorsįor(var m = 0 m < surroundingPoints.Count m++) SurroundingPoints.Add(new Vector3( + offsetI, stepOverHeight.y, + offsetK)) Offset by half of max to get negative distance Nested loop to build surrounding points vector array In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. Think of each unique Scene file as a unique level. LayerMask = Physics.DefaultRaycastLayers & ~(1 surroundingPoints = new List() The most common use of a Ray from the camera is to perform a raycast out into the scene A Scene contains the environments and menus of your game. Here is my layer mask which basically says to ignore the player as a collider/obstacle: The target is the green cylinder in the back of the photo. Basically what I'm trying to do is generate points around an object/check if that object can reach those points, and check if those points can reach the target. ) Īnd later check for if('m working on a raycast based pathfinding system. If((out var hitCoin))Īnd yes of course you could when spawning do var coinInstance = Instantiate (coinPrefab. Or give it a certain component like e.g public class Coin : MonoBehaviour Īnd check for TryGetComponent like if (Physics.Raycast(lastPosition, out hit)) Rather give it either a Tag and check if (Physics.Raycast(lastPosition, out hit))

They simply are not equal but two different objects. Instances (clones) of the coin prefab != the coin prefab reference itself.

If in the scene I drag the instantiated object in the SerializeObject slot of script B the code works, someone can help me? If(Physics.Raycast(lastPosition, out hit)) Calling a bunch of Physics.Raycast might be fine if your project is simple or you target 10 FPS, but in any other case you’ll want to do something else. If (Physics.Raycast(lastPosition, out hit)) Raycasting The Traditional Way in Unity I’ll start by saying what high-performance developers feared and experienced all along: traditional raycasting doesn’t scale in Unity. Ray lastPosition = cam.ScreenPointToRay(Input.mousePosition) Vector3 sizeHouse = house.GetComponent().bounds.size įloat posX = (center.x - (size.x / 2)) + 2 įloat posZ = (center.z - (size.z / 2)) + 2 įloat posHouseX = (centerHouse.x - (sizeHouse.x / 2)) įloat posHouseZ = (centerHouse.z - (sizeHouse.z / 2)) įor (int i = 0 i ().lor = noActive

Vector3 centerHouse = house.GetComponent().bounds.center Vector3 size = floor.GetComponent().bounds.size Vector3 center = floor.GetComponent().bounds.center Quaternion rot = Quaternion.Euler(Vector3.zero) The problem is that the Raycast doesn't recognize the instantiation as the GameObject assigned in the SerializeField, so when I hit the instantiation nothing happen. The script A and the script B use a SerializeField with the same prefab to know which object to spawn (script A) and which object hit (script B). More specifically, what I'm trying to do is spawn randomically 10 prefabs with a script A, then I use a script B where I use a Raycast to hit these objects. I'm new in Unity, and I'm having problem with the use of Raycast on Prefabs.
