I have been having a really frusterating problem with tilemaps recently, where the player/cursor position is incremented differently than where in the tilemap is being displayed.

What I need is a tilemap in which the player/cursor moves at the same speed as the displayed tiles.

I have attempted to correct the issue by using another variable which is incremented/decremented whenever the tilemap moves, but that does not seem to work.

Help would be much appreciated.

Code:

Lbl TILEMAP
ZeroScreen
0->ALLOWZERO
*{FILEPTR->SS
{FILEPTR+1->NS
{TILEMAP->MAPD
{TILEMAP+3->SPTRS
*{TILEMAP+12->TMYM
*{TILEMAP+13->TMXM
*{TILEMAP+9->CCMX/2->CCX
*{TILEMAP+8->CCMY/2->CCY
While 1
   det(49,TILEMAP,SS*TMCX,SS*TMCY
   SetColor(255
   Rectangle(SS*TMCX,SS*TMCX,SS,SS
   *{FILEPTR->A
   Rectangle(0,209-A,A+2,A+2
   Rectangle(A+1,209-A,A+2,A+2
   Sprite({SPTRS+TILIX*3},1,210-A
   *{MAPD+TMXM*TMCY+TMCX->V
   Sprite({SPTRS+V*3},A+2,210-A
   SetColor(0
   FillRectangle(180,201,140,18
   SetTextXY(180,201
   PrintString("tile index:
   PrintInt(TILIX,3
   SetTextXY(180,210
   PrintString("map value:
   PrintInt(V,3
   SetColor(255
   HorizLine(0,220,320
   PrintStringXY("get",1,221
   PrintStringXY("tile-",210,221
   PrintStringXY("tile+",270,221
   Call K
   If K=15 or K=55
      Goto TILESET
   End
   min(TMXM,~1+max(1,1+TMCX+(K=3)-(K=2->TMCX
   min(TMYM,~1+max(1,1+TMCY+(K=1)-(K=4->TMCY
   If K=54 or K=9
      TILIX->*{MAPD+TMXM*TMCY+TMCX
   End
   If K=48 or K=53
      *{MAPD+TMXM*TMCY+TMCX->TILIX
   End
   TILIX+(K=49)-(K=50->TILIX
   If TILIX=NS
      0->TILIX
   End
   If TILIX=~1
      NS-1->TILIX
   End
   If K=56
      Goto EXPORTTM
   End
End


EDIT: made my own renderer for now.
relative offset = absolute offset - tilemap offset

You don't follow this when you draw your relatively offset items, such as the square.

yes, but where do I get those variables?
