Layered graphics

[pikzilla]

How do I use layered graphics? I just want my background to scroll slowly, and my weather effect to scroll slowly as well.

You need to use Parallaxing. There is a Parallaxer extension that works well, or you can set the coefficients in the layer properties.

In the menu bar for MMF2, go to "View" then "Toolbars" then check "Layers Toolbar" This will create a Layer view on the right side of MMF2. Click the + to add a new layer. The bottom layer would be layer 1, then layer 2 displays above that, etc.

However, keep in mind that from what I understand, layer 1 is best used for the main game layer as it's collision mask is calculated at the start of the frame. Any other collisions in other layers are calculated object by object.

What this means is that if you want to position the background layer for parallax scrolling behind the main game layer by making the main game layer at layer 2, your game could lag when scrolling. Depends on how big your levels are, how much action is going on, etc.

Probably best to play around with it some before building a huge project and finding out your game is going to lag too much after you've added a ton of stuff.

Hey stephen, does the parallaxer extension solve the problem of layers lagging with scrolling when the game isn't on layer 1? I've never used that extension.

I've found that using this extension does actually reduce some lag depending on how you are using it.
