Talk:GoldSrc Dimensions

Unit measurements from some Russian forum

Found by @shanocrew on the TWHL discord.

1. The maximum height of objects the player can climb without jumping while standing and crouching = 18 units. 2. The minimum height of the object above the ground necessary for the player to pass under it: upright = 73 units, crouched = 37 units. 3. The minimum distance between objects the player needs to pass between them = 33 units. 4. The maximum height of an object the player can jump on: from standing jump and from squat jump = 44 units, from jump from squat = 62 units. 5. The maximum distance between two objects of the same height that the player can jump: crouch jump = 99 units, walking jump = 109 units, running jump = 239 units, in squat jump = 259 units. 6. The maximum height of an object, the fall from which under normal gravity: will not result in loss of life = 161 units, will cause the player to die = 606 units. 7. The maximum depth of water in which the player does not drown: upright = 53 units, crouched = 30 units. 8. Height of eye lines and weapons from the ground (these lines do not correspond to the actual position of the eyes of the player models): upright = 53 units, crouched = 29 units. 9. If you place the player respawn entities (info_playerstart or info_deathmatch) too close, then if they appear at the same time at the start of the round, one of the players will immediately die because his model will appear in another model's forbidden zone. Therefore, to avoid the autodeath of one of the players, the distance between the subjects of the players' respawns must be at least 50 units. 10. If it is necessary to place an armored wall that cannot be shot with rifles, two thin brushes can be placed parallel to each other. In this case, the minimum distance between them should be 8 units. 11. The maximum distance at which falling raindrops are drawn = 448 units. 12. The map workspace dimensions are 8192x8192x8192 units. 14. The minimum distance between the edge of the map workspace and the boundary brush (including SKY) that does not cause a compile error Brush external world (+/- 4096), = 32 units. 15. Maximum angle of inclination of the wall: from which the player does not fall = 45 degrees; which the player can climb = 70 degrees. Explanation: To set the wall at an angle of 70 degrees to the ground, you must: 1. Check the box Default to 15 degrees of rotation in the Valve Hammer Editor settings. 2. Mount the wall at a 75 degree angle. 3. Hold Shift and rotate the brush 10 places towards the ground. Pressing Shift rotates by 0.5 degrees.

HU to inch conversion

Online it says that HU are also 0.75 and 1.25 inches, has anyone been able to fully confirm which is true?

All of the above. GoldSrc and Source don't use strict irl-based dimensions; they just go by what feels right in-game. It makes sense that Gordon would be 72 inches tall, but a 96-inch door is kinda absurd. Despite this, it looks right in-game, and a more realistic 75-inch door feels too small.
