Its cool to see someone taking an interest into what I'm doing, Your notes look correct to me.

I'm not sure if im even using the 'isSymetrical' tag anymore at this point :D, Symmetry is also kind of buggy. I just messed around with it a little to see if isSymetrical still does what I think it does. and the entire non symetrical builds arent behaving properly. (guess that one goes back on the todo list)

Perhaps I can save a little on the XML file size if I actually didn't store the entire collision shape for symmetrical designs, good catch.

  the last component of the position is actually used for depth sorting. when you change the 'depth' of a component it'll either push it away from the camera or drag it towards it, this way the user can define which things should be on top and which things should be below.

I'm actually planning on making the name a little more complex. currently its not possible to have ship-art components of the same name even if they're placed in different texture atlases(or sub-folders) so... I think I should also add the name of the atlas in these xml files to allow for art bits having the same name.

Looking at this I'd say your bullets are invisible, since their colour is completely black and transparent. In the future I want 'projectiles' to have their own XML's so... in a different editor you'd design your bullets. and then instead of having all this speed/colour/damage information in the shooter components it'd just point to which type of projectile it should spawn.

Pretty much, You can't define a polygon with a hole in it as a single polygon, so if a design has 'negative space' it'll need to keep track of that with multiple polygons, some of them earmarked as holes. (these holes aren't actually used for collision detection, but I am using them to calculate the interior space for the spacecraft and for the new damage system I'm working on.)

Anyway, cool that you're taking an interest. I do think this post might have made more sense in the already existing thread instead of making a new one ;)

that'd be nice. what about special effects for the bullets, like
<effect type="countdownExplosive" timer="10.00" radius="5.43" strength="4.00" blastrgba="(255,255,255,50)" internalPointer="cde_1" useForMain="true">

<effect type="spliterTimed" timer="10.00" objectCount="4" spawnedObject="minibolt">

<effect type="fadeoutTimed" timer="5.67" fadeTorgba="(0,0,0,255)"  fadeback="true">

<effect type="selfDestructTimed" timer="5.67" deathAffects="true" deathAffect="cde_1">
etc. etc.
