Can't get more than one object.

This script works fine until there is more than one door/cube in the scene. Only one of the objects will disappear (if two cubes, only one cube; if two doors, only one door). And yes, I have tried "FindGameObjectsWithTag.

public class Collection : MonoBehaviour

    private bool isRed = false;

    private bool isPurple = false;

    void OnTriggerEnter(Collider other)
    {
        //yellow
        if (other.gameObject.tag == "YellowCube")
        {
            isYellow = true;
            ChangeColorYellow();
        }
        //red
        if (other.gameObject.tag == "RedCube")
        {
            isRed = true;
            ChangeColorRed();
        }
        //blue
        if (other.gameObject.tag == "BlueCube")
        {

            ChangeColorBlue();
        }
        if (other.gameObject.tag == "PurpleKey")

A little more description of your problem would help, I’m not sure what you are trying to achieve and I’m not sure what object this code is on. Are you sure all your objects have the correct tags?
I would make your color bools into a enum though, that will prevent you from have two or more true at the same time. You seem to be trying to set up a finite state machine, you should set up the enum
enum ColorState{ YELLOW,RED,BLUE,PURPLE};
ColorState isColor;
then you switch statements instead of your if statements will clean things up. Also all you change color methods could be one method that takes a parameter:

public void ChangeColor(Color p_color, ColorState p_colorState){
transform.Find(“Body”).gameObject.GetComponent().material.color = p_color;
transform.Find(“Front”).gameObject.GetComponent().material.color = p_color;
isColor=p_colorState;
}

Are you trying to turn on all the objects that share a color on or off?
If so then GameObject.FindGameObjectWithTag is returning one object… you would have to make a List of all the objects that have that tag and then turn them all off in a loop.
But what you could do… a more C# solution would be to make a static function that shows and hides your objects, so when it gets called on one yellow box it gets called on all yellow boxes, this would necessitate a different script for each colored box…
Again I’m not entirely sure what you are trying to accomplish I hope my input helps.
