Tile Engine (tiler,res change,wav & midi player)

This will make it easy for someone to make a cool tile game. The coding on their part will take basicly nothing and produce a quality game. It also has a wav player, midi player and some other stuff. Check it out! The reason I made this is because every place i went to look for a tile engine, either didn't have one or the code was all in the form and was really jacked up. With the engine that I made([email protected]) it is all in a moudle and very easy to understand. It currently supports up to 35 diferent tiles but that can be changed to make it more. MAKE SURE THAT AUTO-REDRAW IS ON! If autoredraw isn't true then you will have to make sure that all the picture boxes that are being used as the input are still visable to the user.
'Newly updated ---- I forgot to add about a transparent bitmap in here, so people who want just that, just steal that and take it. Also I want everybody to know that this engine is fast, because it uses BitBlit ( Bit Blit or Bitmap Blaster) not paintpicture. There is no reason that I can see to use direct-x for a tile engine, BitBlit is fast enough.

Inputs
The map file, if it isn't self explanitory, email me. And the PictureBoxes. Other than that there is some stuff if you want to use the non-engine part of the moudle. The File Name For the WAV, Or MIDI, and the requried inputs for the transparent bliter.

Assumes
TURN AUTOREDRAW ON!!!!!! If something is wrong, just try refreshing the form, in a timer with intraval of about 500 do me.refresh timer1.enabled = false end sub This will make everything better if it doesn't work.

Returns
A BitBlited Form of a large picture produced by many tiles, or even just 1 tile, it doesn't really matter.

Side Effects
Beware of an extreamly cool game made by you with this engine. None Other than that though, if you find one, e-mail it to me and I will correct it and send you the corrected code along with everyone else who reads it, and you shall get some credit for helping me.
