Wire speed/ E2 toMph functions output incorrect speed - Garry's Mod

[media]http://www.youtube.com/watch?v=OBT-SekgUWA[/media] Video explains it. Right now, wire uses the equation inches/second / 22 for miles per hour instead of / 17.6 as it should be. 1 unit = 1 inch, not .75 inch. Confirmed by hitting the source max speed barrier of 220 mph and comparing depth hud speedometer and inches/sec / 17.6 vs wire speedo mph output and E2 toMph output. Actual speed reads 220, wire speed reads 160. Incorrect. Garry doubled the speed limit to 3,800 in/s (default settings for Jinto's physics mod), which equates to 220ish mph.

You're wrong. [url]http://developer.valvesoftware.com/wiki/Dimensions#Map_Grid_Units:_quick_reference[/url]

Yep, it says clearly on the valve wiki that it's 0.75

So you're saying the average human is 8 foot tall? [editline]20th August 2011[/editline] Players are 96 units == 6 feet at 0.75 ratio. For your ratio, it's 8 feet.

Everything is scaled in Half Life 2 on the basis of 1 unit = 1 inch. Player is not 96 units tall. 4' 6" is not an average height of a person, either. [editline]20th August 2011[/editline] I don't think you all quite understand; the actual variable for Gmod's max velocity is 3800. In inches per second that is 215 miles per hour, not 161.

The VDC is wrong about units being 0.75 inch per unit or whatever. The player is 72 units tall. If you treat units as inches then that makes him six feet tall, which is correct for a person. If you assume 1 unit is anything else, then player height is completely wrong and so is everything else. I've tested this extensively. The only reason the VDC says that is because for some reason people like making maps 1/4 bigger than reality so they feel more open and airy. Another example is doorways. Default HL2 doorways are 112 units tall IIRC, which doesn't seem big because everyone's used to them, but stand a player next to them and they look absolutely massive, because they're almost ten feet high. Real doorways are usually 84 inches tall, which interestingly enough is exactly 3/4 of 112. Same applies to ceilings. The average residential ceiling height is 8 feet, or 96 inches. Source ceilings are 128 units. 128 x 0.75 = 96. [editline]19th August 2011[/editline] [quote] Maps, architecture and prop models use a scale of 1 foot = 16 units. Skyboxes (which are 1/16th scale of ordinary maps) use 1 foot = 1 unit. Human Character models for Source Engine currently use 1 foot = 12 units.[/quote] This is wrong. Everything in Source uses the same scale. A 72 unit tall brush or prop will be exactly the same height as a 72 unit player. If 1 foot was really 16 units, then players would be 4 foot 6 inches. I've made 84 unit high doorway props and tested them in-game. They're 12 units taller than the player and thus can be walked through. If the quote from the VDC above were true, it'd be 63 units high and too short to walk through. [editline]19th August 2011[/editline] More proof: Put a prop on the floor, and use Easy Precision to move it upwards 72 units. It'll now be just above the top of your head. Put one in the bottom of a doorway and move it up 112 units. It'll now be inside the top of the doorway. Put it in a normal sized room, move it upwards 128 units, and it'll be just inside the ceiling. Also, PHX small tiles are 12x12 units, which is a square foot. If you make a car six PHX small tiles wide, it's six feet wide, roughly the width of a real car, and it looks correct next to a player. The Volga GAZ wrecked car model in HL2 (car_003) is 71 units wide. The Volga GAZ in real life is 71 inches wide. [editline]19th August 2011[/editline] So the [i]only[/i] way the 1 unit = 0.75 inches theory would be true is if the player was 4 feet 6 inches tall.

[QUOTE=Amplar;31837656][IMG]http://gyazo.com/9537f676c0951cd1d196accd64dfdd79.png[/IMG][/QUOTE] gyazo I see. However, how does this whole unit conversation matter after all?

Proper speed output

The source unit seem to be not standardized unit, because they aren't defined consistently. Once I rebuild some thing from RL in Hammer and noticed that one unit is 0.75 in for brushes. I find the unit system of source a kind of terrible to be honest, would prefer more consistency!

Treat it like 1 unit = 1 inch and it'll be the right size compared to the player, which is the only really consistent reference point you have in Source.
