Collision + scrolling : think about it, you only need to modify the nib{ used for collision the exact same way you modified the nib{ used for tilemapping to implement scrolling.
Scrolling detection : just do a good ol' test. If the character isn't at the center of the screen or if you can't scroll, move the character, else scroll the map.
I sadly can't figure this out ;c
My character is all jumpy and teleporty.
Code:
//From the MOVE source
getKey->K
S->N //X Reset position if on place 1
T->O //Y Reset position if on place 1
If K=1
B++ //Y Offset of Map
T++ //Y Position of Character
End
If K=2
A-- //X Offset of Map
S-- //X Position of Character
End
If K=3
A++
S++
End
If K=4
B--
T--
End
nib{T+B*12+GDB1*2+S+B}->U
And now from the CHECK source, which checks positions and resets them if they're in the wrong place/out of bounds.
Code:
If A>>4
4->A
End
If A<<0
0->A
End
If B>>8
8->B
End
If B<<0
0->B
End
If U=1
N->S
O->T
End
It's a 16x16 map, if that means anything..
I can't find out what to do, but my character doesn't quite follow the camera, he just disappears occasionally and doesn't quite collide correctly :<
EDIT: (I've learned that I need to scroll the screen when my character's in the center, and keep from scrolling when it's viewing an edge of the map.) But I still don't know how i'd do it ;c
I was wondering if there was a way to have more than 10 tiles at once
Of course it is. Just use the correct numbers in any code related to the map. You can also write some code to have width and height for each map, for example store them in the 2 bytes before the map data.
