- Actually, Term and I figured out real life distances in Doom.
- The doomguy is 51 pixels tall, not 56 - his origin is 5 higher than the bottom of his sprite.
- http://cd.textfiles.com/doom2mania/DOOMMISC/FAQS/METRICS.TXT
- According to this, the Doomguy is 5'6", or 66 inches tall. This means that every pixel is 51/66 inches tall.
- Now, pixels in Doom were weird. They're actually 20% taller than they are wide, so to get the width of a pixel, we need to multiply this by 5/6. From this, we get that the width of a pixel is 85/132 inches. One inch is 2.54 cm, so this means a pixel is 2159/1320 cm wide. This is probably the width of a map unit.
- From this, we can get a meter in Doom units.
- doomunit = 2159/1320 cm
- doomcm = 1/doomunit = 1320/2159 du
- doomMeter = doomcm * 100 = 132000/2159 du
- doomMeter ~= 61.1394 du
- An SR50 doomguy can cross about 21.3 units per tic, which is 34.84 cm per tic, or 12.44 meters per second.
- A qucik run through google:
- 12.44 (meters / second) = 27.8274875 mph
- 12.44 (meters / second) = 44.78400 km/h
- Everything you know about Doomguy's speed is wrong.
