Npc strider

Entity description

Strider

Striders are the largest known creatures in the Combine arsenal. Simply parading a Strider through a street can be enough to give players a sense of unease. They are unwieldy and should be used only after great care and consideration. Striders on every street corner is a great way to destroy their effect!

A Strider has three forms of attack: its minigun, which will slowly strafe across targets, its disintegration cannon that will evaporate all dynamic entities it touches, and its legs, which in the right circumstances can stomp down on NPCs and 'immolate' or skewer them. Striders will only attack NPCs; to make them attack parts of their environment/other non-NPCs, use npc_bullseyes.

Striders are large and require plenty of space in order to move around. They need at least 300 units to fit on the ground and around 540 to stand upright. They do not require open terrain though: their long legs allow them to cross over nearly anything up to a certain height.

Scanners can be used to aid a Strider's LOS when properly flagged. Every time they take a photo, the location of all NPCs on it is transmitted to nearby Striders and they will react accordingly.

In Half-Life 2: Episode One, Striders have a new attack. They're capable of firing much faster and accurately than they could in Half-Life 2. They are better at tracking the players movements as well.

Note:Some keyvalues, spawnflags, effect flags, inputs, or outputs might not affect an NPC, based on the functionality and coding of the NPC.
