   I have one scene running, on button click I want to open other
   scene over the running scene, smaller so the first should
   stay in background.

   I tough I can do it with runWithScene

   [[CCDirector sharedDirector] runWithScene:myScene]

   but it says it should be used
   just for the first one.

   - (void) runWithScene: (CCScene *) scene

   Enters the Director's main loop with the given Scene. Call it to run only your FIRST scene. Don't call it if there is already a running scene.

   runWithScene is only for initial startup.

   If you want to load a new scene without stopping the current scene, use pushScene (and popScene to get rid of it).

   If you want to go to a new scene and get rid of the one you're on, use replaceScene.

   @skyhawk is right. Some may disagree, but a Scene is a context in which all logic related to that moment in the game resides. If you feel 2 scenes should overlap like you do then they are actually the same scene.

   I am creating a pause menu so I can't use layers. Can a scene be pushed onto another one but be transparent? I tried using CCLayerColor with a init method of initWithColor:ccc4(0,0,0,75) but that doesn't make it transparent, any help?

   Why?

   Because when trying to pause it like [[CCDirector sharedDirector] pause]; menus become not usable. Unless you could suggest a different method?

   A better solution is to create your own pause method that doesn't call the Director's pause. In my apps, I usually have a method in the layer that will pause all actions for anything that might be moving, unschedule any scheduled methods, etc. Basically, you need to identify all the "stuff" in your scene that needs to be paused, and make it stop where it is. Once you have all that done, then you add the new layer for the pause, and work with that. When you go back to the game, you get rid of your pause layer, and restart everything you paused before.
