iPhone Project: Enlisting Map Creators

Oh right, I get it. Hope it goes well.

Here's the AI code I need to reprogram to work with scrollable maps and in the World Editor:

Code: [Select]

- (void) moveNpc:(NpcData*)npcToProcess currentMapTiles:(NSArray*)tiles allNpcs:(NSArray*)allNpcs {
int target = npcToProcess.target;
CGPoint npcTilePosition = npcToProcess.position;
TileData* npcTile = [[tiles objectAtIndex:npcTilePosition.x] objectAtIndex:npcTilePosition.y];
if (target == -1) //RANDOM
{
int vertOrHorz = arc4random() % 2;
int moveDirection = arc4random() % 2;
if (moveDirection == 0) {moveDirection = -1;}
if (vertOrHorz == 0) { //Vertical
if (npcTilePosition.y + moveDirection >= 0 && npcTilePosition.y + moveDirection < [[tiles objectAtIndex:0] count]) {
TileData *tileToGo = [[tiles objectAtIndex:npcTilePosition.x] objectAtIndex:npcTilePosition.y + moveDirection];
if (tileToGo.npcOn==0 && tileToGo.blocked==0 && (playerData.playerTilePos.x != npcTilePosition.x || playerData.playerTilePos.y != npcTilePosition.y + moveDirection)) {
npcTilePosition.y += moveDirection;
}
}
} else { //Horizontal
if (npcTilePosition.x + moveDirection >= 0 && npcTilePosition.x + moveDirection < [tiles count]) {
TileData *tileToGo = [[tiles objectAtIndex:npcTilePosition.x + moveDirection] objectAtIndex:npcTilePosition.y];
if (tileToGo.npcOn==0 && tileToGo.blocked==0 && (playerData.playerTilePos.x != npcTilePosition.x + moveDirection || playerData.playerTilePos.y != npcTilePosition.y)) {
npcTilePosition.x += moveDirection;
}
}
}
} else //Move towards target
{
CGPoint targetPos;
if (target == -2) {targetPos = playerData.playerTilePos;} else {
NpcData* npcTarget = [allNpcs objectAtIndex:target];
targetPos = npcTarget.position;}
TileData* tilesAround[4] = {nil, nil, nil, nil}; //Up down left right
if (npcTilePosition.y > 0) {tilesAround[0] = [[tiles objectAtIndex:npcTilePosition.x] objectAtIndex:npcTilePosition.y - 1];}

if (tilesAround[2] == nil) {moveableDirections[2] = NO;}
if (tilesAround[3] == nil) {moveableDirections[3] = NO;}

//Place in movement restrictions
CGPoint playerPos = playerData.playerTilePos;
if (playerPos.x == npcTilePosition.x && playerPos.y == npcTilePosition.y - 1) {moveableDirections[0] = NO;}
if (playerPos.x == npcTilePosition.x && playerPos.y == npcTilePosition.y + 1) {moveableDirections[1] = NO;}

if (playerPos.x == npcTilePosition.x + 1 && playerPos.y == npcTilePosition.y) {moveableDirections[3] = NO;}

if (moveableDirections[0]) {moveableDirections[0] = !(tilesAround[0].blocked==1 || tilesAround[0].npcOn==1);}

}

Piece of cake, no?

Certainly looks impressive, but I can't stand un-tabbed code. Tab, tab, tab I say!

I've actually become slightly too rigorous with HTML and JS now though. Most objects are commonly typed on 1 line like so:

Code: [Select]

<img name="subNav3BackgroundButtonImg"src="images/subNav3Background.gif" alt="Designs"width="105"height="44">

But I tab everything:

Code: [Select]

<img
 Â   name="subNav3BackgroundButtonImg"
 Â   src="images/subNav3Background.gif"
 Â   alt="Designs"
 Â   width="105"
 Â   height="44"
>

It's really easy to recognise objects at a glance though.

[Gan]

Ahah, no worries. It is tabbed. When I copy it out of Xcode it untabs and changes the syntax highlight to one color.

[Silverwind]

Ah... I should've copped that. The same thing happened when I posted my own example.

[Gnome]

I think I have most of the forest maps down. Maybe another side quest or two.

Side Quest 1- Destroyed town.


Forest Dungeon 1: Teh Forest (chest TBA)


Forest Dungeon 2: Goblin Camp (Fire pits TBA)

[WarHampster]

Those look amazing! Last weekend was awful, but I will have less work this week, so I should be able to crank out some more tiles.

[Silverwind]

Oh indeed? Well check your PM box, last week I sent you a query concerning snow tiles.

[WarHampster]

Sorry about that, I just replied.

[Gnome]

hehe, well I didn't want to bother WH on tiles we'd only need for one quest, so I appemted to make my own mana pool for the lightning trinket quest...

hehehe

[Silverwind]

Cool.

[WarHampster]

Nice, but why are the side and top tiles darker?

[Gan]

This looks interesting...

[Gnome]

Nice, but why are the side and top tiles darker?

Its more of a joke on how bad i think they turned out. I'm going to fx it later.
