Visualise Physics2D.BoxCastAll
I am working on a 2D game and I just implemented an attack function using Physics2D.BoxCastAll. However I am having a hard time to get the attack hit-box the size I want it to be, since I can't see the box. Is there a way to visualize the box I am casting ? Is Physics2D.BoxCastAll better than turning a collider on and off for an attack function?
@LucasVaz . Physics2D.BoxCastAll returns a RayCastHit2D array. The hit point of each element of that array is the element.point.
Get that point and use it as the center to draw a box. so for example in pseudo code
Vector2 upperLeft = new Vector2( -boxSize.x/2, boxSize.y/2 );
Vector2 upperRight = new Vector2( boxSize.x/2, boxSize.y/2 );
Vector2 lowerLeft = new Vector2( -boxSize.x/2, -boxSize.y/2 );
Vector2 lowerRight = new Vector2( boxSize.x/2, -boxSize.y/2 );
RayCastHit2D[] objectsHit = Physics2D.BoxCastAll ( ...., boxSize, ... );
for each( RaycastHit2D hitObj in objectsHit ){
vector2d hitPoint = hitObj.point;
// draw the box here using hit point as the center and boxSize.x and boxSize.y
Debug.DrawLine( upperLeft +hitPoint, upperRight +hitPoint );
Debug.DrawLine( lowerLeft +hitPoint, lowerRight +hitPoint );
--- you get the idea? continue to draw the other two sides...
}
That should show you the box at each object hit - not tested so my code may need syntax fixes and what not.
