Game slows down when facing left

[Silverthorn]

hmm, I think this is caused by the lf2-engine itself. All lf2-sprites are facing to the right, so when you do something to the left, the exe has to render the sprite the other way round. Depending on your processing power, this can be fast or slow.

I haven't made any tests, but afaik, 2.0a has those bonus-sprites, where you can specify the facing-left/right sprites yourself. So, those sprites would simply be displayed, instead of re-rendered first. According to my logic, this would be faster, but I don't want to solely rely on this.

You could also think about splitting up your sprites. Think if you really need everything. If not... awesome. If yes, well then try the following. Basically, you'd need to opoint multiple objects, each of them displaying one part of the larger image. That's why you'll have to mess a lot with opoint-coordinates. Can get messy if you split many images that way...

I wonder, how large is your sprite? According to your description, it must be in the 4-digit pixel rage...
