Login Action Required

The NinevehGL Forum uses a new concept of "socialized forum" or as we like to say "Tweet Forum".


Here is the deal:
  1. No new registration is required. Just sign in with your Twitter account and authorize the NinevehGL Forum.
  2. Once you’re in, you'll be able to "Follow a Thread", that means every time that thread receive a new post or update you'll receive a mention on your twitter.
  3. Besides, you can enable "Auto Share", then every new post and/or thread you make will be tweeted on your timeline. (By default, auto-share is enabled only for your threads)

Forum Rules:

1. We understand human comunication can become "hot" sometimes. So some insults and bad words ARE allowed. Just don't push too much being an asshole all the time.

2. SPAMMERS are not allowed. There are penalties for this kind of user and they can be banned forever.

3. You can report other users, if you judge necessary. An user reported many times by many people can also be banned forever. However you can also receive penalties for report deliberately for no apparent reason.

If there is a similar thread title, make sure the other one doesn't already have the answer you're looking for.

Hi , I am trying to change Y position of my mesh but doesn't work or compiler gives me an error :

object disappears :

   [_mesh setY:2];


compiler gives me an error :

_mesh.position = nglVec2FromCGPoint(CGPointMake(0, 20));

Hi,

As you can see in the error or even in the header/docs (http://nineveh.gl/docs/Classes/NGLObject3D.html#//api/name/position)

Position is ready only, so you can't set it directly anyway.

Now about your object disappearing is because the camera can be too near.
Use the tween animation to move your object to Y = 2 and you'll see it going out from the screen slowly.

Think about the 3D world space, you have too many options here. You can move the object less than 2, move the object Z instead to get it far from camera, move the camera a little bit, well there are many options, pick the one that best fits for your goals.
