I've recently started developing a simple RPG game in
Basic4GL, so I thought I'd provide some links to useful resources that can speed up development time.
Mappy is a Tilemap editor, so are
tIDE,
Tiled and
Pyxel Edit. (I should just add that if you want the newest version of Pyxel Edit you'll need to pay for it, however they do have an older unsupported version available to download for free.)
There is now a version of Basic4GL that you can use to create Mobile and Web Apps (called unsurprisingly
Basic4GL Mobile) which I paid for a few months ago which should make mobile development a little easier.
Creating your own Tilemaps can be a little tedious if you aren't artistically inclined and prefer programming, so it's good to know that a lot of free ones can be downloaded from
OpenGameArt.
Free Music resources can be found at
Incompetech, and a range of high quality textures, sound-effects and music can be found at the site of
Eric Matyas.
