error: incompatible type for argument 1 of 'movePiece:inDirectionX:inDirectionY:withA

[Chris1979]

Hey guys!

I get the following error message on all 4 cases in the switch function:

error: incompatible type for argument 1 of 'movePiece:inDirectionX:inDirectionY:withAnimation :

why is that?

(I tried to google for the issue but couldn´t find anything.)

-(void) movePiece:(UIImageView *)brickgrid withAnimation:(BOOL) animate{
	
	NSLog(@"MovePiece");
	switch ( [self validMove:brickgrid] ) {
		case UP:
			[self movePiece:brickgrid 
			   inDirectionX:0 inDirectionY:-1 withAnimation:animate];
			break;
		case DOWN:
			[self movePiece:brickgrid 
			   inDirectionX:0 inDirectionY:1 withAnimation:animate];
			break;
		case LEFT:
			[self movePiece:brickgrid
			   inDirectionX:-1 inDirectionY:0 withAnimation:animate];
			break;
		case RIGHT:
			[self movePiece:brickgrid 
			   inDirectionX:1 inDirectionY:0 withAnimation:animate];
			break;
		default:
			break;
	}
}

I also get the following error message on the -(void) movePiece: (UIImageView)brick inDirectionX: (NSInteger) dx inDirectionY: (NSInteger) dy withAnimation: (BOOL) animate{ part

error: can not use an object as parameter to a method

Any suggestions?

 -(void) movePiece: (UIImageView)brick inDirectionX: (NSInteger) dx inDirectionY: (NSInteger) dy withAnimation: (BOOL) animate{
	
(I haven´t done this part yet)

}

The -(void) movePiece: (UIImageView *)brickgrid withAnimation: (BOOL) animate retrieves information from this method

-(void) getPieceAtPoint:(CGPoint) point{
	
	CGRect touchRect = CGRectMake(point.x, point.y, 1.0, 1.0);
	
	NSLog(@"getPieceAtPoint");
	for (int y = 0; y < BRICKHEIGHT; y++){
				
		for (int x = 0; x < BRICKWIDTH; x++){
				
			if( CGRectIntersectsRect([grid[x][y] frame], touchRect) ){
			
				[self movePiece:grid[x][y] withAnimation:YES];
				NSLog(@"X:  %d" , x);
				NSLog(@"Y:  %d" , y);
			}	
		}
	}
}

Thanx in advance!

The problem of 2 errors is related

-(void) movePiece: (UIImageView)brick inDirectionX: (NSInteger) dx inDirectionY: (NSInteger) dy withAnimation: (BOOL) animate{

Yes, you can't use an object, use a reference to that object, so

-(void) movePiece: (UIImageView *)brick inDirectionX: (NSInteger *) dx inDirectionY: (NSInteger *) dy withAnimation: (BOOL) animate{

where you call this method, you are using a reference (but as you declared, should be the object and not the reference)

So just change that line and will work.

Thanx for the fast reply.

I tried it out as you posted. it work fine with the object error

But I got this message instead on the cases in the switch function:

warning: passing argument 3 of 'movePiece:inDirectionX:inDirectionY:withAnimation :' makes pointer from integer without a cast

because 0 and 1 (that you are using when calling the method), are not NSInteger objects are just primitive integers, you need to create a NSInteger or change method definition using int like

-(void) movePiece: (UIImageView *)brick inDirectionX: (int) dx inDirectionY: (int) dy withAnimation: (BOOL) animate{

Now I see it... thanks.. I appreciate it a lot...

I´ve been staring myself blind on this for way to long.

Thanks for enlightening me!
