Adding Slider In Cocos2D
(24 posts) (5 voices)-
What kind of slider, a UIKit slider or one made with cocos2d elements?

Hmmmm.... well I was thinking about doing a post on our blog on a slider I wrote in Cocos2d... I suppose now I'll have to do it, let me get back to on that.

I did a quick post with all the source, heres the link:

Actually.. it's not because of the new Touch code in 0.8. You'd pretty much have to change the 3 touch functions in SliderTouchLogic to look like this, notice the comment where you'd want to preserve the "newer" code:
- (BOOL)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; //rest of began code is the same } - (BOOL)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; //rest of moved code is the same } - (BOOL)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; //rest of ended code is the same }I saw your other question about 0.8.2, all you needed was a libz.dylib it'd be worth your while to get it to compile.

Edit: but it works in simulator

Hmmm those are strange errors, doing a quick google search on that type of error seems to indicate that your project settings are not set to the correct "simulator" or "device" settings... maybe take a look in the settings, could even compare them to the working examples from the cocos2d source folder.

Epic thread revival, but I just wanted to say thanks to @mobilebros for this Slider! I used it to replace my UIKit sliders that were not rotating with cocos2d autorotate functionality. I just modified your files to be compatible with the latest version of cocos2d :)

MemberSo, I tried out this slider, and well, I got it working, but the code is less than straightforward for one, and two, some of it doesn't work!
I want to set the value to a default, i.e.
[slider setValue:1.0]; and it does nothing! The slider's thumb object just remains in the middle.
So, the Slider works in that you can grab it, drag it, and it will set the value you want it to, but you can't initialize it to be at a certain position.
OR, if you can, please let me know! I like that this item is a CCMenuItem, that's why I didn't roll my own solution, but now I'm at Alpha and need to fix these bugs...

@horseshoe7, I used the slider in a previous version of cocos2d (I think about 0.99.0) and they worked great then, the setValue worked perfectly, however, I tried to implement them just yesterday in 0.99.5 and I too am unable to set a default with setValue. I have been scouring the code, but haven't found anything yet. Hopefully @mobilebros has some time to check it out.

Ok I'll take a look in a bit, and post it in a more accessible location.

Ok I had a chance to look, it was something silly of course; I was using a member variable directly (position) and it wasn't getting "dirtied". I posted the src here, the zip is all that's needed:

Just to recap, 'cause it took me a second to remember too, here's the link to the old post:

So that variable 'position' was being used from a parent class of a dif ccnode?
EDIT: Sorry, I just looked at the new source, I understand now!! Thanks @mobilebros!

Thanks very much @mobilebros - all working in my 0.99.5 ported app now :)
