Size
The size spawnarg is used to setup a default collision model for entities when they do not have a CM in either the model file or a separate .cm file. If used, it also defines the size of the frob box (see the item within the section Frobbing#Entity Settings
size has three dimensions X,Y,Z centred on the centre of the volume of the entity (NOT the entity origin.)
By default it creates a box. To create another shape, use the following spawnargs with the number of desired sides as the value:
Examples:
"size" "8 20 32"
The above would create a box of 8, 20 and 32 units in X, Y and Z direction.
"noclipmodel" "0" "size" "8 20 32" "cylinder" "5"
The above would create a 5-sided cylinder of 8, 20 and 32 units in X, Y and Z direction.
"noclipmodel" "0" "size" "8 20 32" "cone" "7"
The above would create a 7-sided cone of 8, 20 and 32 units in X, Y and Z direction.
Notes:
This spawnarg is disabled if the spawnarg noclipmodel is set to 1, or if mins and maxs are defined.
Making a dedicated collision model should always be prefered over using this method.
