How can I make such an interface with cocos2d for iphone? Cortex interface
I already made a subclass of CCSprite and override the draw
method like this:
-(void)draw {
ccDrawCircle(CGPointMake(480/2, 320/2), 70, 0, 50000, NO);
ccDrawCircle(CGPointMake(480/2, 320/2), 25, 0, 50000, NO);
ccDrawLine(CGPointMake(480/2, 320/2+25), CGPointMake(480/2, 320/2+70));
ccDrawLine(CGPointMake(480/2+25, 320/2), CGPointMake(480/2+70, 320/2));
ccDrawLine(CGPointMake(480/2, 320/2-25), CGPointMake(480/2, 320/2-70));
ccDrawLine(CGPointMake(480/2-25, 320/2), CGPointMake(480/2-70, 320/2));
}
The problem is that I don't have any control over the circle (can't set the position of it)...and i don't know how to place text/images into these "cells". Another problem is the touch detection..mayby just cgrects? but what if i have more than 4 cells and one cell is "rotated"?
Any ideas?
I think you have two options here, but I don't recommend subclassing CCSprite, infact very rarely would recommend doing so, theres almost no need to.
In my opinion, you could do either of these to get your image.
1. Use OpenGL to draw your image.
2. Use CCSprite to draw your image. (Cleaner)
Once you have drawn it, its simply a matter of creating it when you press down on the screen. Once you press down on the screen (or any prescribed object) I would then employ a simple trigonometric solution.
This is the algorithm I would use:
(PSUDOCODE):
dx = currentpos.x - sourcepos.x
dy = currentpos.y - sourcepos.y
mag = sqrt(dx*dx + dy*dy);
ang = CC_RADIANS_TO_DEGREES(atan2f(dy/dx));
if (ang > 0 && ang < 80 && mag > kMinMagnitude) //Load Twitter
if (ang > 80 && ang < 120 && mag > kMinMagnitude) //Load facebook
I don't think making a subclass of CCSprite is the right choice here. You will probably want a NSObject that creates the CCSprites for you.
Also CCSprite.position = CGPointMake( X, Y )
should allow you to set the position of the sprite. Don't forget to add it to a layer just like any other CCNode object.
