  1. Hi, I'm running into an issue regarding collision detection against adjacent DisplayObjects. Let's say I have sibling objects that are a child of a Container that has been rotated. If I use getBounds() on the siblings they return a bounding box that is oriented to cardinal north. Using those bounds for collision detection may result in false positives, because the given bounds may not follow the actual shape and orientation of the DisplayObject. I created a codepen to illustrate the point: When you toggle the "rotate" buttons at the bottom of the pen you will see the purple box morphing to the shape of the bounds for "shape" and "label". The text will change from red to green if the collision detection returns positive. I would like to do a more robust collision detection algorithm (possibly based on Separating Axis Theorem), but I would need to grab the vertices for each shape correctly translated to the global coordinates regardless of their nesting within the scene graph (accounting for scale, rotation, and translation from the shape and all parent transforms). The case being that the collision detection that I would like to do may not be only between direct siblings within the scene graph. Is there a nested property that would give me what I'm looking for, or will I need to grab the graphics data and apply all of the recursive parent transforms myself for each vertex? Here is a fork of a codepen that demonstrates the Separating Axis Theorem:
  2. Hi guys, I'm working in a project and emerged a matter about how to do hitTest?Who can help? thanks!
  3. Hi Guys Frogive me if this is a silly question but how do I do a hit test using pixi? if(hitTest(obj1, obj2)){ do something}; I'm busy writing a function to do this but I would imagine there has to be an easier way. Thanks for your help Lemons
  4. Hi forum, I am working on a proof of concept for a game where i need to be able to place buildings (like any RTS you know). I already have some terrain generation going (I do not use tilemaps) with trees and later on other stuff. I'd like to know if it is possible somehow to calculate where a user can place buildings, and possible even draw (using PIXI.Graphics) a green colored area (around the building) where it is possible to place / install it. Circle based collisions would help at this stage, but alpha channel transparency checks would be better: i have tree textures as transparent 256*256 and 512*512 PNG's with shadow, i'd like to know when a building is being placed right near a/some tree(s). http://www.powergeek.nl/proj/mongento/versions/5/ (no preloader, working version. zooming is buggy but too lazy to work on that right now :> ). Thanks for any tips / pointers!
