I'm getting ready to build my first real level, so I thought it would be a good idea to figure out some do's and don'ts.
I've searched for this info on the forum, but most posts were of older versions, so I don't know what's changed. I also thought some answers were a bit vague, so I want to make sure I get things cleared up.
Let's assume that we are making a fairly large level, and we need to fill it up. Maybe we'll target a standard resolution of maybe 720p, but our layout needs to be big enough to provide a worthwhile level for a platformer, so at least maybe 3000 to 4000 px or more.
Now, we want the level to look as good as we can, but at the same time not need a supercomputer to run well. We might even want to put it on mobile platforms as well.
Here is a chart showing some ways to fill the level. The numbers are just placeholders for example purposes.
A: we could fill the entire level with a sky, maybe just use a single color and using a tiled background.
B: we could fill areas with single color tiled backgrounds that are a bit smaller
C: we could fill large to medium sized areas with fancy tiled background for areas we want detail
D: we could make a bunch of individual sprites to fill the areas
E: we could make a bunch of sprites but each one would use an animation frame (like the platformer tutorial I read on here).
F: we could use background tiles that are various sizes broken down into chunks and then placed side by side
G: we could use sprites that are various sizes broken down into chunks and then placed side by side
H: we could use moderate sized tiled backgrounds like 500px by 500px
I: we could use moderate sized sprites like 500px by 500px
So, I mean we have a lot of choices for what we use to fill out the level. On one hand, we can end up with a lot of objects if we use smaller sprites. On the other hand, we can have fewer objects but larger images to work with.
I figure we will use a combination of sizes. I just need to find out what the limitations are so I know what will break the game and make it run poorly.
I've read warnings about using too many objects and warnings about using too large objects. I'm trying to figure out where the best comprise is before I start working hard on detailed artwork.
