keep the gameobject inside the circle and not exceed the circle-CodePudding

How to keep the gameobject(Red ball) inside the circle and not exceed the circle.

CodePudding user response：

Maybe you can try this, to keep the Red inside the circle.

float radius = 100; //radius of white circle
Vector3 whiteCenter = circle.transform.position; //center of white circle
float distance = Vector3.Distance(Red.transform.position, whitePosition);

if (distance > radius){
Red.transform.position = whiteCenter;
}

and if you want to limit movement in a circle

if (distance > radius){
    Vector3 fromOrigintoObject = player.position - whiteCenter;
    fromOrigintoObject *= radius / dist;
    player.position = whiteCenter   fromOrigintoObject;
    Red.transform.position = player.position;
}
