  1. POHow do I use tile coordinates instead of the regular coordinates in cocos2d
    text
    copied!<p>I am still new to cocos2d and I have this problem that when I am using the ccp coordinates it stays at same position even when I move to the next screen. I came to the conclusion it must be that I am not using the tiles coordinates. So I need some help converting.</p> <pre><code> - (CGPoint)tileCoordForPosition:(CGPoint)position { float x = floor(position.x / map.tileSize.width); float levelHeightInPixels = map.mapSize.height * map.tileSize.height; float y = floor((levelHeightInPixels - position.y) / map.tileSize.height); return ccp(x, y); } -(CGRect)tileRectFromTileCoords:(CGPoint)tileCoords { float levelHeightInPixels = map.mapSize.height * map.tileSize.height; CGPoint origin = ccp(tileCoords.x * map.tileSize.width, levelHeightInPixels - ((tileCoords.y + 1) * map.tileSize.height)); return CGRectMake(origin.x, origin.y, map.tileSize.width, map.tileSize.height); } </code></pre> <p>that is what i use to translate regular coordinates into tile map coordinates.</p> <p>now I am trying to spawn an enemy at a certain position specifically (0,0)</p> <pre><code> -(void)addsaw{ CCSprite *saw = [CCSprite spriteWithFile:@"saw.png"]; // Determine where to spawn the target along the Y axis CGSize winSize = [[CCDirector sharedDirector] winSize]; int minY =saw.contentSize.height/2; int maxY = winSize.height - saw.contentSize.height/2; int rangeY = maxY - minY; int actualY = ( rangeY) + minY; //THIS IS THE PROBLEM RIGHT HERE saw.position = ccp(0,0); [self addChild:saw]; // Create the actions id actionMove = [CCMoveTo actionWithDuration:actualDuration position:ccp(-saw.contentSize.width/2, actualY)]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished2:)]; [saw runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; saw.tag = 1; [_saws addObject:saw]; } </code></pre> <p>How do I change the ccp of my addsaw so I can have it spawn at the tile (0,0) rather than the cocos2d regular (0,0) </p>
