the "mapcollide" example does not seem to work properly in 1.1.x. jumping doesn't seem to work, and it looks a lot different from the way it did in 1.0. here is what it looked like in 1.0.x: here's how it looks to me since 1.1.3: and jumping doesn't seem to work. i rely on the examples to make sure i'm doing things right, so when the examples are broken, it makes me uneasy. any thoughts? thanks!
