how to reference GameObjects to GUIButton???
i have this code, and every GUIButton have to be reference to each GameObject but still appearing in the same place all the GUIButtons. . how do i put them to follor each GameObject?
code:
public GameObject cube1;
public GameObject cube2;
public GameObject cube3;
public GameObject cube4;
void Start()
{
Screen.orientation = ScreenOrientation.LandscapeLeft;
}
void OnGUI()
{
Vector3 V = Camera.main.WorldToScreenPoint(gameObject.transform.position);
if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube1"))
{
//do something
};
if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube2"))
{
//do something
};
if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube3"))
{
//do something
};
if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube4"))
{
//do something
};
}
The position of the buttons is relative to the gameObject with this script on it. Not relative to the cubes.
You are on the right track. You need to convert the world coordinates for each cube to screen coordinates. Try this:
void OnGUI()
{
Vector3 V = Camera.main.WorldToScreenPoint(cube1.transform.position);
if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube1"))
{
//do something
}
V = Camera.main.WorldToScreenPoint(cube2.transform.position);
if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube2"))
{
//do something
}
V = Camera.main.WorldToScreenPoint(cube3.transform.position);
if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube3"))
{
//do something
}
V = Camera.main.WorldToScreenPoint(cube4.transform.position);
if (GUI.Button(new Rect(V.x,Screen.height - V.y,100,30),"cube4"))
{
//do something
}
}
Note, your code will anchor the upper left corner of the GUI.Button to the center point of the object. To anchor them on centers, you will need to offset V by 1/2 of the button width and height before making the GUI.Button() call.
