The only problem I see of using 8x8 tiles is that it is a shooting game, and it might be difficult to see where the enemy is if you can't see far, which will be the case with 8x8 tiles.
What you could do is draw everything in an appvar and use Runer's Pixelmapping to have fast scrolling and pixel based detection. But good luck inserting Runer's code in yours :P

Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.

Rough AI Workflow:
1) pathfind to back of opposing player
2) if opponent turns around to face you, run away.
3) if opponent is in line of fire, shoot.

That's exactly what I need for this, thanks :)

I wouldn't do the tilemap thing anyways, since then I had to completely rewrite everything. But before I include something like this, I going for the AI first:

Rough AI Workflow:
1) pathfind to back of opposing player
2) if opponent turns around to face you, run away.
3) if opponent is in line of fire, shoot.
Makes sense. 2) and 3) quite are easy, but I might need help with pathfinding.

changing the size of the tiles does not necessitate changing the size of the player or of bullets; not wanting to have to rewrite things is understandable, though. good luck =)

I haven't really done pathfinding before, so I'm probably not gonna be able to help you there.

This is just guessing but distance formulaing the eight directions with pixel testing? I'm pretty sure there are better ways. XP

THe game's name is my idea! :D Great job! But when I was thinking about the name, iI thought about a totally other game genre ^^

If I were you, I'd check out Builderboy's recent contest entry. You might not understand the code, but there's a pathfinder that calculates the significance of nodes based on a dynamically generated tilemap. PM'ing him might be good if you want to go through with this, but it will be fairly challenging :P

I saw the project a while ago. Never thought of it that way. I might ask him.

Wow the new updates made a huge difference, it looks really fun! I'm excited to see where it'll go. I agree with leafy and the others that a larger playing area (using larger tiles, if you'd like) would be pretty cool. Also, i think it'd be much better to compare the coordinates of the bullets to your map/player data rather than pixel tests. That would also let you shoot overtop of the items (i don't know if you can do this now?), add background tiles, and would probably be much faster.

Though now, rereading through some of your comments ("I wouldn't do the tilemap thing anyways, since then I had to completely rewrite everything."), i'm not sure if you are using a tilemap or not..?

Ok, to clear thinks up a bit, here is how the stuff works:

I have a 168 byte save file, which contains the data of the map (scaled down to 1/4 because of resolution with 2x2 pixels; 156b), the spawn points of the players (4b) and the key setup (8b). How the resizing works can be found here.

The data is extracted to L3, top and bottom lines are added with another Fill( function at the very beginning. The backbuffer is used for collisions. It isn't at all change during the game. The bullets, the players and the power-ups are displayed only on L6, but they check collisions only with the constant stuff on L3. That makes it possible to walk over grenades and pass other players, as well as shooting "through" power-ups. Bullets won't pxl-test whether they hit a player, that's done with a simple subtraction and a comparison to the threshold for both X and Y. Pxl-test is only used on the backbuffer. In every frame, L3 is copied to L6 and all the other stuff "ors" over that on L6. No ClrDraw / DispGraphClrDraw to avoid another bcall().

I couldn't do much on this, I've been working on another "scientific useful" project for some time now, but nonetheless here is an update:  :)

Added:
  • Automatic Archive/Unarchive safe file (no big deal, but was missing before)

Changed:
  • Fixed phantom grenades / grenades exploding much too late / grenades disappearing (occurred when both players throw a grenade the same time)
  • Downgraded the machine gun: only 9 shots, fire rate reduced from 200% to 150% (recommended by a friend)
  • Reduced grenade timer by 20% (explodes after 80 frames)

Since it isn't an update with changed graphics / major changes on game mechanics, I won't add a screeny.
