Hi
Im new to extencion development but think a specific extencion would help tidy up alot of my Event editor.
...
In my Event Editior i have alot of custom 'box collitions', wich look like this:

Many of theese collision conditions are tree times as big ( containing up to 12 'inserted conditions' )
...
Im thiking that an extencion wich checks for 'box collisions' ( as in the code above ) in just 1 line/ condition would help me tidy up my code alot.
This is also a good excuse for me to start with extencion developemnt, since what i am trying to do is rather simpel.
...
My consern however is that the application i am trying to develop is meant to be played on mobile devices and other platforms, not just Windows PC.
...
When and if i create an extencion, how hard is it to make it compatible with other application build types ( example SWF, XNA etc )?
Any advice as to what i should do, should i go for it or just leave this alone?
