A fast, easy to use, free, and community supported 2D game engine
I have TileMaps working and you are able to move around a single tile map fine, but what i would like to do is have a much larger map that can be handled directly by Cocos2d in a single map. ie. 300x300.
I would like to break the map up in to smaller chunks say 30x30 and then have 10 maps, when the user is playing I would like to place the correct map to allow for seamless scrolling.
Any suggestions on how to go about this?
Thanks for any assistance.
Suppose you want a vertical scrolling.
There are 10 rows of 32 * 32 tiles that cover the whole screen.
You also have and aditional row that is off screen.
You could move the tiles down, and ask if they have gone offscreen, then if they did, move them on top of the topmost tiles, that would repeat ad infinitum.
Can anyone confirm this actually works? I am about to start doing some tile work and i would like to know if this is possible. Thanks!
Thanks for the reply.. I guess I kind of forgot about this post.. For a side/top down scroller your method would work. The issue we had was it's an ISO map, and we like being able to zoom in and out. Since we wanted to zoom out much further we came up with another solution.
I kind of tossed out the tile engine that was built in and coded my own. I didn't like several of the base features in the TMX handling. Mainly only being able to support a single tile atlas per layer. It just wouldn't work for our game, since we have single animations that take up an entire 1024 texture.
The other issue is the built in TMX code doesn't really handle the Z order very well on ISO maps. While you could use the VertexZ stuff, I found that our frame rates dropped significantly. Which we really didn't like. After the redesign we went from 20fps (2G) using VertexZ to my method which gave us 50fps (2G). Even the 3GS would drop to 40fps using VertexZ on a 60x60 map (we have 1000+ sprites that require proper Z ordering) with my code it runs at 60fps.
At some point down the road I might wrap up the code and submit it to the project, right now it's very generic and builds maps dynamically, and it requires some things to be done via code. In the future I'll probably fix it so it's a little easier for other people to work with.
Oh, and you can easily do what you want replacing tiles. Keep in mind though you will need to handle a few fundamental things, like animation and stuff outside of the tile sheet. Certainly though you could run through an infinite loop easy enough replacing tiles at a scrolling rate easy enough for a side/top down scroller.
Although you will have the same limitation imposed on all tile maps using TMX, one texture per layer.
