#import "HelloWorldLayer.h"

CCSprite *player;

float maxspeed = 3;

float rotatestep = 4;

int leftOrRight;

CCMenuItem *btnL;
CCMenuItem *btnR;

// HelloWorldLayer implementation
@implementation HelloWorldLayer

+(CCScene *) scene {}

-(id) init
{ if( (self=[super init])) {
player = [CCSprite spriteWithFile:@"Icon-Small.png"];
player.position = ccp(240, 160);
[self addChild:player];

CCMenuItem *btnL = [CCMenuItemImage itemFromNormalImage:@"Icon-Small.png" selectedImage:@"Icon.png"];
CCMenuItem *btnR = [CCMenuItemImage itemFromNormalImage:@"Icon-Small.png" selectedImage:@"Icon.png"];

btnL.position = ccp(30,30);
btnR.position = ccp(450,30);
[self addChild:btnL];
[self addChild:btnR];


[self schedule:@selector(steer) interval:.02];
}
return self;
}


-(void)steer {
float speed = maxspeed;

if (btnR.isSelected == YES) {
player.rotation += rotatestep*(speed/maxspeed);
}

if (btnL.isSelected == YES) {
player.rotation -= rotatestep*(speed/maxspeed);
}
}

- (void) dealloc{}
