| 02:59.25 | khonkhortisan | it's not real |
| 03:11.43 | khonkhortisan | Is the tail of a shot dangerous? If I shoot, the shot stays in the center of the screen. If I'm close to a wall and the shot ricochets slightly right, the tail instantly moves to the left of the screen on rico. If I'm close enough to the wall, even though the shot is always travelling away from me, my tank can explode. |
| 03:12.27 | blast007 | the tail is just visual |
| 03:13.52 | khonkhortisan | Then how can I get shot by driving close to a wall and ricocheting a shot slightly to the side? |
| 03:14.17 | khonkhortisan | I mean a corner of a wall |
| 03:14.37 | blast007 | so you're saying that you get different results when you turn off the tail and without moving your tank? |
| 03:17.45 | khonkhortisan | If I'm South of a compass-aligned building, and I go east enough to shoot the right side of the SouthEast corner, so the shot turns less than say 30° clockwise, and I drive forward while shooting, when I get close enough to the building, I explode. It doesn't work if I just use a wall (I think because I have to be closer than the corner of the tank allows) |
| 03:18.43 | blast007 | well, anyways, the tail has nothing to do with it |
| 03:18.46 | khonkhortisan | Shots shouldn't have any size, so I know I'm not shooting the wrong side of the building |
| 03:19.08 | blast007 | I don't even think that shots have a "width" as far as the death check goes - just a point |
| 03:19.43 | khonkhortisan | It'll be more understandable if I make a video of it, I think I'll come back to it sometime later |
| 03:23.57 | apeman | its because your tank has a dying size as well as a physical size, and it can be larger than the wall |
| 03:24.13 | apeman | extend beyond the wall |
| 03:24.25 | khonkhortisan | I'm looking at my radar, and the shot doesn't hit that rectangle |
| 03:24.34 | apeman | rectangle means nothing |
| 03:24.38 | blast007 | there's also a half sphere check, iirc |
| 03:24.49 | blast007 | and that might be what is used for shot hit calcs |
| 03:25.19 | blast007 | (or, that might just be used as an initial check because it is faster than a box check) |
| 03:50.44 | khonkhortisan | http://youtu.be/S-CsSqigYQs |
| 03:51.02 | khonkhortisan | I always thought the rectangle meant something |
| 03:56.49 | khonkhortisan | If I do the exact same thing without rico, the distance that I would normally explode is close enough to the wall that I don't see the explosion sprite, only the glow |
| 03:57.34 | apeman | the zoomed in rectangle means your physical dimensions, that is for interacting with buildings |
| 03:58.34 | apeman | you are right that the explosion with rico is just as close if not closer |
| 04:00.36 | khonkhortisan | I shouldn't be able to shoot myself unless the shot turns at least 90° |
| 04:01.42 | apeman | shouldn't, in expectation. But give any mathematical definition of hit and it will have some practical weakness |
| 04:02.05 | apeman | the one in use right now is simply worse than it should be though |
| 04:07.04 | khonkhortisan | Shooting a corner gets me closer to the point of ricochet than shooting a wall gets me |
| 04:08.03 | khonkhortisan | and most people just don't go around shooting corners |
| 04:16.33 | apeman | what are you trying to do anyway? Understand it? Change it? Complain? |
| 04:18.19 | *** part/#bzflag smoooth (~smoooth@cpe-071-074-011-155.ec.res.rr.com) |
| 04:18.37 | khonkhortisan | I've played bzflag long enough that I didn't expect that to happen | I wanted proof of how to recreate it in case someone eventually wanted to fix it | I wanted to know if it was normal/expected or not |
| 04:20.13 | khonkhortisan | it caught me off guard, I was driving around and shooting with the joystick hat |
| 04:21.18 | apeman | the part where your tank has a different hitzone to the physical rectangle is normal |
| 04:21.25 | apeman | your tank is fat |
| 04:21.45 | apeman | and its like the rico hits your arm, thats how fat |
| 04:22.01 | apeman | fatter than the rectangle |
| 04:22.39 | apeman | shots are literally a moving point. no radius, explosions dont do anything |
| 04:23.06 | apeman | however |
| 04:23.26 | khonkhortisan | So the shot starts in the physical tank, goes into the hit tank, ricochets before leaving the hit tank, the shot gets a new start point that isn't a tank, realizes it's in a hit zone and explodes? |
| 04:24.01 | apeman | the shot actually starts outside the tank |
| 04:24.32 | apeman | if u look closely you see the shot appears outside both your physical tank and your hit radius |
| 04:24.33 | khonkhortisan | but it ricochets before leaving the hit zone? |
| 04:24.41 | khonkhortisan | oh. |
| 04:25.08 | apeman | but you are also on to a "bug" or weirdness of the calculation |
| 04:25.34 | khonkhortisan | it's not physically correct, for one thing |
| 04:26.14 | apeman | when you go close enough to wall, the shot starts not only outside ur tank but it starts where it would rico |
| 04:26.44 | apeman | for example close to wall the shot starts inside you |
| 04:26.58 | apeman | and then you die as it exits you |
| 04:27.51 | khonkhortisan | The shot can start behind the camera too (proof being shooting a wall without rico) |
| 04:28.53 | apeman | no, thats just the shot appearing for 0.01 seconds (1 frame) and exploding |
| 04:29.23 | apeman | you never see it because it breaks in wall the same instant its fired |
| 04:29.42 | khonkhortisan | then I mean the explosion image appears behind the camera |
| 04:30.07 | apeman | explosion has nothing to do with the killing properties of the shot |
| 04:31.21 | apeman | im pretty sure it wont get fixed anyway |
| 04:32.47 | khonkhortisan | well anyway the physics are better than a certain unnamed kart racing game |
