The ice gun will have the following effects. It has been proposed by sheepluva that it take the appearance of a large freezerspewing ice cubes. The cubes will be visual gears only. The scatter from them and the impact snow dust should help hide imprecisions in things like the GearsNear effect.For now we assume a "ray" like a deagle projected out from the gun.All these effects assume the ray's angle is not changed and that the target type was unchanged over a number of ticks. This is a simplifying assumption for "gun was applying freezing effect to the same target". * When fired at water a layer of ice textured land is added above the water. * When fired at non-ice land (land and lfLandMask and not lfIce) the land is overlaid with a thin layer of ice textured land around that point (say, 1 or 2px into land, 1px above). For attractiveness, a slope would probably be needed. * When fired at a hog (land and $00FF <> 0), while the hog is targetted, the hog's state is set to frozen. As long as the gun is on the hog, a frozen hog sprite creeps up from the feet to the head. If the effect is interrupted before reaching the top, the freezing state is cleared.A frozen hog will animate differently. To be decided, but possibly in a similar fashion to a grave when it comes to explosions. The hog might (possibly) not be damaged by explosions. This might make freezing potentially useful for friendlies in a bad position. It might be better to allow damage though.A frozen hog stays frozen for a certain number of turns. Each turn the frozen overlay becomes fainter, until it fades and the hog animates normally again.*)procedure updateFuel(Gear: PGear);var t:LongInt;begin t:= Gear^.Health div 10; if (t <> Gear^.Damage) and ((GameTicks and $3F) = 0) then begin Gear^.Damage:= t;
