It`s bed time now and i didn`t read your code very carefuly, excuse me for that.I have to go early in the morning, but also wanted to reply here.
So my question is are you good with using primitives only?
Do you consider to replace them at some point?
Because if you are good with primitives, i`m making level editor for myself and haven`t builded object library yet, it uses dbpro primitives, so there is not much i need to add in it to make it work for you.
You can place objects in space, save file, and if i provide you loading routine you can load the levels in your game.Everything is in very basic stage now, and there is no much time to develop it further, but anyway i can push myself a little to help you, so you can be the first ever test it.
That is one solution, but i`m not sure how much time it`s gona take to provide you with working version of the editor, that can be useful for you.
Other solution is to read more tutorials and start some simple project for now(and give me some time and a way to reach you when i`m ready with the editor), i`m not discouraging you.But in general you can`t just ask things like that here.Is not that is forbiden but anyway there is not much people that can help you, even if there is, next thing you will do when they help you is asking about some general stuff again.
Your question sounds like: "Hi, guys someone knows how to make PROTOTYPE II?LINEAGE III? WORLD OF STARCRAFT?OR DIABLO IV?"
Bet on tutorials for now, i know they are pain when you are new, but this is the way to do things right.Asking about complicated stuff like loading levels, specially when you allready build the first one, means that you lack experience and skill, you aim too high.
Where there is a will, there is a way.
I often edit my posts, that`s who i am
