Thanks dreamerman and fuzzy70,

I will read that tutorial when I get time, I'm at work now, but I do understand my mistake.

Thanks for looking

I will clarify the L4 variable.  Its just toggled with a key press so I can turn on or off each layer.

I added that in after reaslising it was drawing the player on top.


ah thats it.

its drawing the player ever iteration.

I need to only draw the player once like you say

Would looping through the map twice be bad?

EG:

Code (glbasic) Select Expand


FOR u = 0 TO w
FOR v = 0 TO h
IF (u+x_off<=map_data.width) AND (v+y_off<=map_data.height)
IF L1 THEN DRAWANIM 0,map[u+x_off][v+y_off].L1_tile,x+(u*tile_height),y+(v*tile_height)
IF L2 THEN DRAWANIM 0,map[u+x_off][v+y_off].L2_tile,x+(u*tile_height),y+(v*tile_height)
IF L3 THEN DRAWANIM 0,map[u+x_off][v+y_off].L3_tile,x+(u*tile_height),y+(v*tile_height)
ENDIF
NEXT
NEXT

DRAWANIM 1,7,(Player.X*tile_height)-(x_off*tile_height),(Player.Y*tile_height)-(y_off*tile_height) // Player

IF L4
    FOR u = 0 TO w
FOR v = 0 TO h
IF (u+x_off<=map_data.width) AND (v+y_off<=map_data.height)
                    DRAWANIM 0,map[u+x_off][v+y_off].L4_tile,x+(u*tile_height),y+(v*tile_height)
                ENDIF
        NEXT
    NEXT
ENDIF


Good morning,

I'm not sure if this is a bug or I am doing something wrong.

I have a tile map engine that has 4 layers and a player.

It renders them in this order.

Layer1
Layer2
Layer3
Player
Layer4

Only it is always showing the player on top of everything.

At first I thought it was the ID of the sprites so I loaded the same file again with a different ID and set that for layer 4 and it still renders the player last.

Some code and screenshots:

Code (glbasic) Select Expand



LOADANIM "TILES.png",0,32,32  // 0 is the handle
LOADANIM "player.png",1,32,32 // 1 is the handle

FOR u = 0 TO w
FOR v = 0 TO h
IF (u+x_off<=map_data.width) AND (v+y_off<=map_data.height)
IF L1 THEN DRAWANIM 0,map[u+x_off][v+y_off].L1_tile,x+(u*tile_height),y+(v*tile_height)
IF L2 THEN DRAWANIM 0,map[u+x_off][v+y_off].L2_tile,x+(u*tile_height),y+(v*tile_height)
IF L3 THEN DRAWANIM 0,map[u+x_off][v+y_off].L3_tile,x+(u*tile_height),y+(v*tile_height)
DRAWANIM 1,7,(Player.X*tile_height)-(x_off*tile_height),(Player.Y*tile_height)-(y_off*tile_height) // Player
IF L4 THEN DRAWANIM 0,map[u+x_off][v+y_off].L4_tile,x+(u*tile_height),y+(v*tile_height)
ENDIF
NEXT
NEXT



I turned off rendering the first 3 layers for this shot



I then made the changes as below and got this (with the layers all intact)

Code (glbasic) Select Expand



LOADANIM "TILES.png",0,32,32  // 0 is the handle
LOADANIM "player.png",1,32,32 // 1 is the handle
LOADANIM "TILES.png",2,32,32  // 2 is the handle

FOR u = 0 TO w
FOR v = 0 TO h
IF (u+x_off<=map_data.width) AND (v+y_off<=map_data.height)
IF L1 THEN DRAWANIM 0,map[u+x_off][v+y_off].L1_tile,x+(u*tile_height),y+(v*tile_height)
IF L2 THEN DRAWANIM 0,map[u+x_off][v+y_off].L2_tile,x+(u*tile_height),y+(v*tile_height)
IF L3 THEN DRAWANIM 0,map[u+x_off][v+y_off].L3_tile,x+(u*tile_height),y+(v*tile_height)
DRAWANIM 1,7,(Player.X*tile_height)-(x_off*tile_height),(Player.Y*tile_height)-(y_off*tile_height) // Player
IF L4 THEN DRAWANIM 2,map[u+x_off][v+y_off].L4_tile,x+(u*tile_height),y+(v*tile_height)  // Additional tile set
ENDIF
