yeah I kinda agree with AP. I think it's best to add a limit so the user won't need to code it himself. If he wants a greater limit then he just change a number. Less risks of messing up

What does a tilemapper do exactly?

{AP} · « **Reply #62 on:** April 18, 2010, 06:18:21 pm »

It basically reads map information (stored however the tilemapper wants) and then displays a map on the screen based on that information.
Usually contains scrolling or map changing if scrolling isn't supported.

it basicly just scrolls an 8x8 tile map, Pic3 holds the actual data for the tiles, pic4 holds the sprite you use. so if the Pic3 says 0, it will use the first sprite in Pic4. If it says 1, it will use the next sprite in pic4. I'm pretty sure it is like Sir's, but I'm not sure if his scrolls. yeah, I probably should have added a limit to the Y movement, but wasn't sure what it should be (and wanted it variable without actually using a variable, ie I'd like to change something at the beggining of the program instead of deep inside the program, without using a different variable, eh oh well). give me a sec to update the code with a Y limit of 8.

Edit: beaten to it

Thanks, _player.
Sorry, if I sounded kinda like an asshole in my message, but it kinda had to be said.
I still thank you for the contribution. Minus the bug, it looks great.

Ah ok, I think I get it then. That's cool. Thanks, both of you, for explaining

Some programmers starts programming games by hardcoding collision detections. In some cases this works OK but in the end your code becomes massive because you have an entire program for per room and some rooms are considerably slower. I wonder if that's what games like Final Fantasy VII, VIII, Legend of Dragoon and Star Ocean 2 do

i don't understand how this routine gets a tile. could someone explain it in depth?

Code: [Select]

Lbl GT  ; X position in S, Y position in T.  Returns tile
S/7->S  // Swap 7 for the size of your tiles
T/7*7->T  // Yes, I know it is /7*7.  Leave it that way.  Unless you don't have 7x7 tiles, in which case you should change the values accordingly
If S^2
{(S/2)+T+GDB1}^16
Return
End
{(S/2)+T+GDB1}/16
Return

sorry for bringing up an old post, but it seems like a useful topic to keep alive anyway.

Well, Axe doesn't support floating point numbers, or numbers with a decimal. Therefore, if you have 7x7 tiles, dividing it by 7 will return the tile number, instead of the pixel number. Then, {(S/2)+T+GDB1}^16 returns the second nibble, and {(S/2)+T+GDB1}/16 will return the first nibble.

For the half byte tilemap, you can only display total of 16 sprites per map, even if the sprite size is less than 8*8, right?
And for the one byte tilemap, can you display total of 16*16 sprites? (too lazy to do math

)
How big are the data in the Axe tho? Like, let's say I want 30x50 map with one byte tilemap. How much memory does it take?

_player1537 · « **Reply #70 on:** June 05, 2010, 10:20:48 am »

30x50, 1500 bytes. for the first question and the second, yes.
Edit: fail, 30x50 is 1500 not 150 woops

jsj795 · « **Reply #71 on:** June 05, 2010, 10:46:22 am »

oh okay, and the half-byte 30X50 would be 750... lol i got it^^
I thought it would be more, like how in BASIC the matrix is huge

Btw I think Kindermoumoute would appreciate if someone could translate this tutorial into French. I could maybe do it but I suck at grammar and the french I would use isn't always understandable by non-Canadian users (the reason why I almost always speak English with Silver Shadow and Lionel Debroux, despite all of us speaking French as native language)

Hey Sir, any chance of this thing maybe getting updated or anything? Just curious

DJ Omnimaga · « **Reply #74 on:** July 19, 2010, 08:15:58 pm »

I think this was discontinued because he was working on a bigger and better tutorial including that stuff. However, I have some doubts it will be worked on soon, judging he last said that months ago and that he now focuses on his OS, IDE and maybe will revive his contest entry or something
