how to change object's B color when object A is in range? 2D
I have an enemy AI object that randomly patrols a top down 2d maze(object B) and within this maze are tiles(multiple objects of A). I'm having trouble figuring out a way to change any tiles that is within close distance to the enemy object B. Here is my code:
public Transform blocks;
private void Update()
{
blocks = GameObject.FindGameObjectWithTag("Breakable_Block").transform;
if (Vector2.Distance(transform.position, blocks.position) < 10)
{
blocks.GetComponent<Renderer>().material.color = Color.green;
}
}
Thanks in advance!
Good day.
Look at your code:
GameObject.FindGameObjectWithTag("Breakable_Block") is a single object
you can go find all blocks, and check all of them if...
public Transform[] blocks;
private void Update()
{
blocks = GameObject.FindGameObjectsWithTag("Breakable_Block").transform;
foreach (Transform OneBlock in blocks)
{
if (Vector2.Distance(transform.position, OneBlock.position) < 10)
{
OneBlock.GetComponent<Renderer>().material.color = Color.green;
}
}
}
Now, you check all the blocks positions, 1 by 1, and thatones thar are closer than 10, will change its color.
Bye!
hello and thank you for answering my question. I've applied your code but I get this error.
