libgdx collision detection / bounding the object
- by johnny-b
i am trying to get collision detection so i am drawing a red rectangle to see if it is working, and when i do the code below in the update method. to check if it is going to work. the position is not in the right place. the red rectangle starts from the middle and not at the x and y point?Huh
so it draws it wrong.
i also have a getter method so nothing wrong there.
bullet.set(getX(), getY(), getOriginX(), getOriginY());
this is for the render
shapeRenderer.begin(ShapeType.Filled);
shapeRenderer.setColor(Color.RED);
shapeRenderer.rect(bullet.getX(), bullet.getY(), bullet.getOriginX(), bullet.getOriginY(), 15, 5, bullet.getRotation());
shapeRenderer.end();
i have tried to do it with a circle but the circle draws in the middle and i want it to be at the tip of the bullet. at the front of the bullet. x, y point.
boundingCircle.set(getX() + getOriginX(), getY() + getOriginY(), 4.0f);
shapeRenderer.begin(ShapeType.Filled);
shapeRenderer.setColor(Color.RED);
shapeRenderer.circle(bullet.getBoundingCircle().x, bullet.getBoundingCircle().y, bullet.getBoundingCircle().radius);
shapeRenderer.end();
thank you
need it to be of the x and y as the bullet is in the middle of the sprite when drawn originally via paint.
