It exists a map editor for glbasic?
Tnk1000.
no. not yet :whistle:
2D or 3D?
There is an example 3D map creator in the Showroom. There are numerous third-party 2D and 3D map editors available that will work with GLBasic.
but you have to write a wrapper for this mapeditors
Not unless you want to make it more complicated than it needs to be. For 2D, at the most you might have to write a simple loader to parse the map file. For 3D most of the map editors will export to X format (and others) and should work fine with GLBasic's converter.
*edit* I should note that with my continued bad luck, the map editor I like best and have done the most work with only exports to the B3D format, LOL.
