我制作了一个健康栏以保持在敌人上方，但它并不总是在敌人的中心

Question

Health bar image is a children of an "Screen Space - overlay" Canvas and it has this code inside of it

void Update()
    {
        var wantedPos = Camera.main.WorldToScreenPoint(Enemy.position);
        transform.position = new Vector3(wantedPos.x, wantedPos.y + 40, wantedPos.z);
    }

but the problem is the health bar apear above enemy but it's not always in the center of enemy

here is a video to explain the problem more https://youtu.be/ZMWKxJvjy2o

Answer 1

So looks like you are taking the centrepoint of the enemy, converting that point into screenspace, and then moving vertically up on screen to get your health bar position. It seems to work ok but u get that undesired effect.

I dont really know what you want, but you could start with a higher point in world space.

Instead of Enemy.position, make a child gameobject of the enemy that is higher up, closer to the enemies head, use that position instead of Enemy.position, and maybe reduce that 40 number.. It might be closer to what u want.
