I don't quite get what you mean.... do you mean how to make the sprites? Or how to make a tile-map and then scrolling a scrolling map?

I mean how to make a tile map and then scrol a scrolling map (sprite stays on the same place of the screen, so there isn't a sprite-movement but a scrol-movement)

And how about the sprite's x and y, what corner is it?

Well, first to drawing a tilemap...
xLib has a nice function for it

copied from the readme

Spoiler For tilemap:

So, with scrolling, I'd do that you have a grand matrix with the full map in it, and into a second matrix is copied what must be displayed on the screen, which is used then for the tilemap function. Then I would place the sprite for the character in the center using the overwright logic and then update the LCD.

I don't really get it, if you once have time (now or tommorow or whenever, could you give me an example of tilemap + scrolling? Sorry to bother you with my n00b questions

Ok, do already know how to use matrixes?

stevon8ter · « **Reply #35 on:** May 27, 2012, 04:56:37 pm »

Not really, but now i allready installed xlib, yeey

Ok, matrices can be used just as two-dimensional lists. You have in total 10 matrices (with xTravar up to 255

)
Well, you can defind them like this:

Code: [Select]

[[5,6,8][8,6,2][3,5,2->[A]As you can see this is a 3x3 dimensional matrix that is stored in A.
You can call the single thingys like this: [A](row,column) (row and column may be the other way around, dunno

)
you can also define them like that
Get it?

stevon8ter · « **Reply #37 on:** May 27, 2012, 05:02:13 pm »

Yeah, get that

Sorunome · « **Reply #38 on:** May 27, 2012, 05:07:36 pm »

Ok, now you can use that to store tiles in it, twelve across and 8 down, for 8x8 tiles.
Now, you have in a pic all the tiles stored.
0 would draw then the first tile, 1 the second one etc. 96 and greater automaticly fetch from the next pic.
so, now you have:
real(2,0(if you use [A]),0,0,0,12,0,8,<picnum>,0(method),8,1)
Caution: I didn't try this out now, it may crash, as wrong drawing of tilemaps in xlib can make the calc crash.

Is it like: one tile has to be in the pic and then it always takes the same tile or does the tilemap has to be in the pic allready completely?
And the matrix has to be preset with the numbers you've set in the previous post?

Sorunome · « **Reply #40 on:** May 27, 2012, 05:23:35 pm »

Well, you have in the pic then all your tiles you wanne use, e.g. grass, roads, etc.
then the one in the top left corner is represented by the number 0, the one left to it with 1 etc.
Now the matrix has all the numbers in the way it should be displayed in the correct positions.
Nope you get it

stevon8ter · « **Reply #41 on:** May 27, 2012, 05:28:18 pm »

And how does the matrix interpretes (wrongly spelled) it? Oike the left-above matrix is the left above tile where he places the tile-number?

Sorunome · « **Reply #42 on:** May 27, 2012, 05:31:34 pm »

Yep, so for the full screen you need a matrix the size of 12*8, and then everything is then just exactly copied.

stevon8ter · « **Reply #43 on:** May 27, 2012, 06:18:58 pm »

But in the real( are standing 11 numbers, in xlib's tutorial are standing 14 numbers

Sorunome · « **Reply #44 on:** May 27, 2012, 06:22:43 pm »

ups, sorry

usage: real(2,0,0,0,96,64,0,12,0,8,<picnum>,0,8,1
and the matrix, as a tilemap for the full screen would be then 12 tiles across and 8 tiles down your matrix will be 12 across and 8 down

Code: [Select]

[[2,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1][1,1,1,1,1,1,1,1,1,1,1,1]]->[A]

that would fill it with the tile 1 and just in the top left corner have the tile 2.
