Description Convars Keyvalues Flags Other Weapons


weapon_psp is the entity name for the UMD launcher found in SMOD. Similar to the spinfusor weapon from Tribes(video) and even shares some sounds.

Primary Fire: Fires a small optical disc that explodes on contact.

Secondary Fire: Jabs the square button. If a disc has jammed on the way out, this will fix the problem.

  • weapon_psp_discdamage <integer> ( Default: 100 )

    Sets the angular positioning (Pitch, Yaw, Roll) of the entity.
  • model <string>
    Sets the model of the entity.

    Sets the distance at which the entity model starts to fade. (0 : use fademaxdist)
  • fademaxdist <float>
    Sets the maximum distance at which the entity model is visible. (0 : don't fade out)

    The scale factor that gives some control over fading. Using 0 turns off the forced fade values.
