There is also the notion of 'menu anchor', which where on the page you want the grid to be. There is a notion of 'Screen fraction', which is how much the grid of items takes up on the page. Note The formulas for getting the items spread across several pages can be a little tricky.

In the example Scene below, I just used a simple menu. If you want, you can put the menu into a layer (so it has background that moves). The control buttons on the scene start an action to move the layer 100% to the left (if they move right) or 100% to the right (if they move left).Īll of these are attached to a single 'Menu', which is what the actions are applied against. You will have to space all the items so the items for the first page are on the visible part of the screen and the next group is 100% off to the right, the third group is 200% off the right, etc. Place all your menu items, including the control arrows for ALL pages on it. Define the PlatformsĪdd the following struct in HelloWorld.This is the way I have done this in the past.I had a game with the option for the player to select multiple space ships, 4 per page, with back/forward arrows on each page as well.

For info on how to setup cocos2d-x project, refer the official wiki.Īll our code will go into `HelloWorld` class that comes with the template. I will directly dwelve into the platforming mechanism here. I am not going to discuss about how to setup a cocos2d-x project for iOS here. Mid Project (with just the platforms render)Ģ. Before diving in, here is the demo video showcasing the final output:ġ. It might not be the best solution out there, but it is something that works. I tried implementing the platforming physics logic in cocos2d-x and it came out pretty well as per my expectations.
