What does 1 unit equal?
One of the most common question asked about "units" in Goldsource is what real-world unit they correspond to. Unfortunately, 1 unit doesn't really equal anything. It is not a "real" inch or centimeter. It is just a figure. If you build your maps based on a unit actually representing a standard measurement, then Gordon will end up being a short fat person.
So what dimensions should I use?
These dimensions apply to Half-Life maps and other mods that don't have custom player movement.
The following figures are pretty good, but if you're making small spaces for players to fit through, it's best to add a few units just to be sure. A unit is the smallest square available in the 2D views. Just use your
key to reduce the size of your grid until it won't go any smaller, then zoom in with the
key, and the grids should be one unit. You can verify this by checking the Snap on Grid
indicator at the bottom right of the screen.
Ground obstacle height
This is the maximum height, in units, an object can be while still allowing the player to walk over
Overhead obstacle height
This is the minimum distance, in units, that can be between the ground and an object while still allowing the player to pass underneath
Minimum path width
This is the minimum width, in units, that can be between two objects while still allowing the player to pass between
This is the maximum height, in units, an object can be while still allowing the player to jump on top
Running crouch-jump: 62Note:
Some users have reported that it is possible to crouch-jump 64 units high provided the surface you jump up to is sloping down towards you between 45° and 0°.
This is the maximum distance, in units, that can be between two objects of the same height, while still allowing the player to jump from one object to the other
Running crouch-jump: 259Note:
These values are approximate, as jump distance can be extended using various movement techniques.
Looking directly ahead, a point will appear to be at eye level if it is 64 units above the floor.
|Height of fall (units)||Damage done|
If a player falls in water they will not suffer damage, even if the water is only one unit deep. If you require the player to be damaged in a water fall, use a trigger_hurt
entity with a damagetype
of 32 (FALL)
