Checking if player is near any certain gameobject

Questions & Answers

So I am trying to make it so that when my player is near any gameobject with a certain tag it sets a bool to true, How do I do this I have been trying many different ways and have got it to work by going distance = Gameobject.find(“Sprite”).transform.position then saying if(distance < 1) Boolean = true. But this only works with one gameobject and it is not using tags.

Another approach could be this:

bool CheckCloseToTag(string tag, float minimumDistance)
{
    GameObject[] goWithTag = GameObject.FindGameObjectsWithTag(tag);

    for (int i = 0; i < goWithTag.Length; ++i)
    {
        if (Vector3.Distance(transform.position, goWithTag*.transform.position) <= minimumDistance)*

return true;
}

return false;
}
To use it just call the method whenever you want, for example:
void Update()
{
…
yourBoolVariable = CheckCloseToTag(“sprite”, 10);
}

with this you can cast everything within a radius

void caster(Vector2 center, float radius) {
        Collider2D[] hitColliders = Physics2D.OverlapCircleAll(center, radius);
        int i = 0;
        while (i < hitColliders.Length) {
            if(hitColliders*.tag=="CertainTag")*

{
//do something
}
i++;
}
}
}
