Just curiosity i guess, But What does UpdateWorld() realy do? I understand the need for it to Update Animation in mesh's and Collisions stuff, but what else is is responsible for?

I think that's it really... Putting a value in the brackets updates the animation at a different speed.

I think that's about it.....but I'm not really sure...

If you use the command MoveEntity, does the entity move immediately? Or does the entity actually move when UpdateWorld is called (and reset the move-command after executing it)? If the entity only moves when UpdateWorld is called, then I should use multiple UpdateWorld's in the main loop. Even if it doesn't, I should use multiple UpdateWorld's, because Blitz doesn't handle collisions between moving objects very well. I'm trying to create a space game and want the player-ship to collide with AI-ships (and vice versa). Before the first UpdateWorld, I would move all AI-ships. Between the first and second UpdateWorld, I would move the player-ship. This way Blitz can do it's collision checking for each object-type separately, so the player-ship doesn't move through any AI-ship when both are moving. If UpdateWorld also moves the entities that are told to move, does Blitz reset the move-commands to zero, so the next UpdateWorld doesn't move them too? If that would be the case, then the AI-ships would move twice as fast. Can anyone explain this to me?

MoveEntity has nothing to do with updateworld(). You can move entities around and check there updated positions. You don't even need Renderworld for this. Renderworld simply draws whats there :o)
