Hello,
If I've good understood the "//set size and look into world" commentary, UTIL_SetOrigin
set the size of the model to the entity.
I'll explain my thought :)
To set the size of an entity, there's two different solutions :
- point-based entity : UTIL_SetOrigin(...), UTIL_SetSize(pev, Vector(...),
Vector(...))
- solid based entity : UTIL_SetOrigin(...), the size is automacally set to the
model's one
(I don't know if it uses the hitboxes or the polys to calculate the size).
Hope you've understood what I think :)
For the solidity problem you could also set pev->solid to SOLID_BSP... I don't know if
it works but it's worth
thinking over...
