How Was Fly1 Made?
« on: December 24, 2011, 12:22:54 AM »
In fly1, when you reach the end of corridor you don't teleport, but keep going right back to the beginning of the corridor without losing any speed. It's a bit hard to explain and a screenshot doesn't help. I included the map.

If anyone can explain it decently I'll give you a congrats smack on the ass. It's probably something simple, but I have no idea.

Thanks

The way it's done in this map isn't possible without creating a leak, so you should never try to copy this to your own map.

Basically, the corridor takes up the whole width of the map, from -4096 to +4096 units. The game stores player coordinates in the form of eights of one unit, i.e. a change in position of 1 = 0.125 units. The positions are stored in a 2-byte integer, which has 65536 possible values. This is where the maximum map size comes from: 65536/8 = 8192 possibilities, which are mapped from -4096 to +4096. When you get "past" the edge of the map, the number containing your coordinate wraps-around, i.e. if you're at (4095, 0, 0) and you move 1 unit forward in the x direction, you will find yourself at (0, 0, 0). Because you never actually touched the wall, your velocity remains the same.

As to what Chef-Killer says, I think it is possible if you used a tweaked compiler, I will do some tests.

mine 170, you need about 165 speed to "make" the jump :P

Ah that's about the only way left for me to try. It's a pretty neat way to use the confines of bsp to your advantage. Thanks.

180... with wall strafing instead of strafing. And you can do the jump way below 165. Check out the replay on the q2 server, luum's time is pretty wild.

The way it's done in this map isn't possible without creating a leak, so you should never try to copy this to your own map.

Is there a different way to do it without creating a large leak then?

Idk, I made just guess based on my jump

Put a lot of rooms after each other :P
Now srsly i think sometimes teleports ports you with speed you gained before the port. Not sure how it happens but I think sometimes it does. Cant reproduce it tho.

I guess it would be worth a shot to try, it'd be pretty cool if a way was figured out to make it without a leak.

Ah, I only thought about the current tools and not about the possibility of a tweaked compiler.
