Projectile help

[Betanol]

I came up with a not too much sophisticated projectile. A red shiny plasma ball. But there is a problem.. It keeps passing through middle textures. Even if I put block everything, impassible and etc, it keeps passing through. I don't know what is hapening. Any ideas?

Here is the projectile:

Code: Select all

ACTOR InsPlasma
{
   Radius 1
   Height 4
   Speed 40
   Damage 5
   PROJECTILE
   +Floorclip
   +RANDOMIZE
   alpha 0.75
   SeeSound "weapons/plasmaf"
   DeathSound "weapons/plasmax"
   States
   {
   Spawn:
      IPLS AB 8
      LOOP
   Death:
      IPLE ABCDE 4
      Stop
   }
}
