Custom Bounds Calculation with Hull

[peterje]

In a project I am working on I wish to have bounds for my display objects be more accurate than a rectangle. For example, this balloon sprite currently collides with everything in its default AABB bounds. However according to the documentation I can override calculateBounds   and define a hull for this object. How might I go about that for a large collection of sprites I have stored as a PNG? Do I have to manually map out the hull for each sprite or is there a built in algorithm to do this for png with transparent backgrounds?

use PhysicsEditor to make a hull

use hitArea or override containsPoint() for interaction. As for bounds, they are always rectangle

Thanks. Not sure what PhysicsEditor is..not much comes up when I search for it. Is it a tool separate from PIXI? Also, what is the point of the hull if the bounds will always be rectangle. Does this mean I can't have better collision detection than AABB?
