I am using dbSpriteCollision() to dectect Collision between my character and the attached image. Is there any way to make it so my character can walk through the tannish area and with dbSpriteCollision() only for the green walls? Do alpha channels just make the sprite transparent?


Edit: Fixed it I just created an array of my sprite through Mappy. Solid is 1 and anything else I can walk through. Here is the collision code:


Attached is my Zelda demo. Zelda 4! xD There are still a few bugs left though. Thanks guys.

The dbSetSpriteAlpha command makes all of the tan invisible if set to that color. You need to make the maps tile-based.

I think that's where the tree sprites are from.

Do some googling. Something like "2d tile based", and see what comes up. There are some good tutorials out there.

if i where goign to do it i would set up an array of interegers. that would represent the screen. then i could asign each "tile" a number that would allow me to assign it properties. eg if a "tile" in my array = 1 then its solid and you can't move to that tile. if its a 0 its open ground and you can walk on it if its a 3 then its lava and you can move on it but you take damage etc etc etc

thats how i would go about doing it to start. But i would agree, google is your FRIEND!

Yep! The, it's just a matter of drawing functions for the tile map. But, Google will teach you to do that in more detail than we can here.

OK. I have found a neat tool called Mappy that creates 2d tile based maps. Does the 2D array and the image(Bitmap file type) go hand and hand? Example: does Testmap_map0[0][0] = Top left square of the Bitmap? Would I use dbLoadBitmap() to draw my image to the screen? And Google didn't really help me much. You guys did.

yeah [width,height,tileproperties] so you eg[0,0,0] = your image id for the top left square [0,0,1] = your tile property (can you walk on it ?) etc.

im guessing that program you mentioned takes your image and it just cuts it up in to blocks ?

It creates an array based off a map you create with Mappy. The only problem I'm having is dbLoadBitmap() is not displaying anything.
