I noticed the working example link was broken so I've updated it. I also improved the NPC template and added the revamped Roguesoft logo to the main menu screen.

btw, is the template easy enough to understand? As in, do you feel you could use it in your games?

Wow, now that's streamlined! Ah, but old Silver knows his grid navs... the lowest I can get it in GM is 23 lines:

Card Script
Code: [Select]
gridMap$ = "1111111100000110000011000001100000110000011111111"
playerSpriteX = 137
playerSpriteY = 137
SPRITE 1 playerSpriteX playerSpriteY Player 1.gif

Keydown
Code: [Select]
ON KEYDOWN
  playerNewSpriteX = playerSpriteX
  playerNewSpriteY = playerSpriteY
  IF keydown$ = "UPARROW" THEN playerNewSpriteY = playerSpriteY - 44
  IF keydown$ = "DOWNARROW" THEN playerNewSpriteY = playerSpriteY + 44
  IF keydown$ = "LEFTARROW" THEN playerNewSpriteX = playerSpriteX - 44
  IF keydown$ = "RIGHTARROW" THEN playerNewSpriteX = playerSpriteX + 44
  playerNewGridY = playerNewSpriteY / 44
  playerNewGridX = playerNewSpriteX / 44
  playerNewGridX = playerNewGridX + 1 
  playerNewGridY = playerNewGridY + 1
  playerNewGridXY = 7 * playerNewGridY
  playerNewGridXY = playerNewGridXY - 7
  playerNewGridXY = playerNewGridXY + playerNewGridX
  playerTile$ = MID$ gridMap$ playerNewGridXY 1
  IF playerTile$ = "0" THEN playerSpriteX = playerNewSpriteX
  IF playerTile$ = "0" THEN playerSpriteY = playerNewSpriteY
  SPRITE 1 playerSpriteX playerSpriteY
END KEYDOWN

I'm not particularly fond of the streamlined versions however, as they only handle the bare minimum of features.

But its so very easy to add to it. Adding door support is almost as easy as just adding a method.

Here's an example of what can be done with a little tinkering:

Giant player sprites. The only difference to the code is the "playerSize" variable in the player property block, and the "giant sprite" collision routine. If you set "playerSize" to 1, collision will be calculated as normal. If you set it to 2, collision will be detected on a 4x4 tile radius.
Code: [Select]
' --- Edit these vars to set the attributes of the grid.
gridMap$ = "1000001100000010000101000000100100010000001000001"
gridSize = 7
tileSize = 44

' --- Edit these vars to set the attributes of the player.
playerSprite$ = "Giant Spider.gif"
playerGridX = 1
playerGridY = 1
playerMoveSpeed = 16
playerSize = 2


' --- Determine the player's sprite coordinates based on its grid coordinates.
playerSpriteY = playerGridY * tileSize
playerSpriteY = playerSpriteY - tileSize
playerSpriteY = playerSpriteY + 5
playerSpriteX = playerGridX * tileSize
playerSpriteX = playerSpriteX - tileSize
playerSpriteX = playerSpriteX + 5
SPRITE 1 playerSpriteX playerSpriteY $playerSprite$$

'------------------------------------------------------------------------------------------------

ON KEYDOWN
  playerNewGridX = playerGridX
  playerNewGridY = playerGridY

  ' --- Check which direction the player wants to move in.
  IF keydown$ = "UPARROW" THEN playerNewGridY = playerGridY - 1
  IF keydown$ = "DOWNARROW" THEN playerNewGridY = playerGridY + 1
  IF keydown$ = "LEFTARROW" THEN playerNewGridX = playerGridX - 1
  IF keydown$ = "RIGHTARROW" THEN playerNewGridX = playerGridX + 1

  ' --- Check what kind of tile the player is trying to move onto. (check if it's traversable or not)
  playerNewGridXY = 0
  playerNewGridXY = gridSize * playerNewGridY
  playerNewGridXY = playerNewGridXY - gridSize
  playerNewGridXY = playerNewGridXY + playerNewGridX
  playerTile$ = MID$ gridMap$ playerNewGridXY 1
  IF playerTile$ = "0" THEN playerTile$ = "Empty Tile"
  IF playerTile$ = "1" THEN playerTile$ = "Obstacle"
  IF playerNewGridX < 1 THEN playerTile$ = "Obstacle"
  IF playerNewGridX > gridSize THEN playerTile$ = "Obstacle"
  IF playerNewGridY < 1 THEN playerTile$ = "Obstacle"

i agree, so how bout we streamline a system with features, who can get the least amount of lines?

Sure! How about traveling to neighbouring rooms, teleporters and dialogue invokers?

Wow thats amazing! (I wonder if thats possible with gm) [thinks] (probably but it would run very slowly I would imagine)
EDIT: Well heres my shot at V7 with GM (I used imagefile with overlay) Click Here

 it loaded a few trees but it didnt seem to work for me.

whats gms sprite limit? cause sc v7 uses over 80 sprites. i suppose you could load the ground texture (like grass) as one large sprite so it only has to load the obstacle sprites

I didn't use sprites I used imagefile. Did you enable imagefile command uses overlay. When I load it up it seems to be disabled I had to enable it twice. Its in game options.

Like Tireas said, go to Game Options in the Go menu and make sure "IMAGEFILE command overlays" is checked. It works correctly if you do that. For some reason the uploaded file had it disabled.

Ah, but subsisto panton! While that's certainly a very impressive routine for handling map decor I can't help but notice that the method for handling collision detection remains entirely the same as V6, and I feel it necessary to remind you that the V in the V series has up until present referred to the version number of the navigation engine alone and not the additional routines used in conjunction with it. I therefore must regrettably inform you that I cannot concur in the recognition or existence of a V7 navigation engine.

Hoping this letter finds you in good health,

your old friend,

Doctor A. Van Helsing
