libgdx collision detection on moving and rotating object (rectangle enemy)

Newbie & Debugging Questions

hi
i am trying to get collision dectection working properly but when i do it, the collision area keeps moving. no matter what i tried. there are 2 objects and the objects are moving and i cannot get the area of the collision to follow the enemy/object. i am using the method below to see if the collision will work and it does not follow the enemy properly.
the above is an example of how i am using the sprite extension. the object/enemy is a sprite from libgdx the class is extended by sprite.

below is the render of the shape so i can see if the collision area is working.


shapeRenderer.begin(ShapeType.Filled);
shapeRenderer.setColor(Color.RED);

shapeRenderer.rect(rect1.getX() + (rect1.getWidth() / 2), rect1.getY()  + (rect1.getHeight() / 2) - 2, rect1.getOriginX() - 1, rect1.getOriginY() - 4, 1.0f, 1.0f, rect1.getRotation());

shapeRenderer.rect(rect2.getX() - 10, rect2.getY() - 10, rect2.getWidth() - 10, rect2.getHeight() - 10, rect2.getOriginX(), rect2.getOriginY(), rect2.getRotation());

shapeRenderer.end();

this is in the enemy class collision check


rect.set(getX() + (getWidth() / 2), getY()  + (getHeight() / 2) - 2, getOriginX() - 1, getOriginY() - 4);

this is to see if the enemy is colliding


public boolean collides(Ball ball) {
		if (getX() < ball.getX()) {
			return (Intersector.overlaps(ball.getRect1(), rect));
		}
		return false;
	}

You’re going to need more code than that. All that tells me is you’re rendering 2 rectangles, doesn’t say anything about where you’re doing movement or collision checking.

#3

Do you update your rect according to the position of your player and enemy?

On update-

update player’s position
update rectangle that corresponds to the player

Same goes for the enemy…

i have updated the code
