Quake3World

I guess most of you will know what trickjumping is. What I'd like to know is: WHY does it work? Is is a bug in the code or something different?

Depends on the trickjump skill you mean.

Take for instance strafejumping. In Q1, it was an oversight of the developers on how vector math works, so I suppose it qualifies as a bug (esp. when you take into consideration that it's frame rate dependent). As to how it works, it's basic Pythagoras: your speed is 320 units p/s. When you move in a straight line, it's exactly that. But with strafejumping, you move along the longest edge of a triangle so your speed is something like sqrt(320^2 + 320^2) =~ 453 units p/s. You sweep the mouse so you stay at that edge with each server frame. If you didn't, you'd be moving in a straight line again.

Hope this makes sense. Don't hesitate to say so if it doesn't.

Oh, and overbounces are definitely a bug. If you drop straight down from certain heights, you'll be just a tiny bit below the floor when the server frame runs. As a stop-gap measure, the game reverses your z axis velocity.

heh thanks i never understood strafe jumping until you put it that way. Same with overbounce bug.

For the purists on strafing.

Strafing isn't like that any more is it? I've tried it once: running both forward and sidewards should make you faster, but I couldn't notice any speed improvement.
Bunny hopping: The game just doesn't apply any friction although the player hits the ground, right? That's what I've read some time ago.

Never seen this article before, nice one.

Play a little bit of DeFrag and do that while paying attention to the UPS counter...you'll notice the difference if you turn the mouse.

^^^^ thanks. My head hurts. I would really like to spend the time to read that thoroughly and I will.

How do I do a backflip?

F, F, B, B, L, R, jump.

Thank you. Would it help if I wore loose pants?
