Both methods require some finessing. The NPC won’t jump down if it is too far and in the first method the animation is already set so you need to use landing points that match.

Police rappel and jump
First Combine Police
Second Combine Police
Note.pngNote:This is an extension of the WiseNPCrappel.

The sample file for this project, at the page bottom, illustrates:

  • Combine Police Rappels from ceiling then jumps down to join the attack.
  • Second Combine Police jumps down from above and begins to attack.

As you see there are two methods of getting NPC’s to jump down from heights illustrated in this project.

  • The first method is a scripted_sequence that begins when the rappelling Combine Police has completed its rappel.
  • The second method uses info_node_hint entities to get the Combine Police to jump down.

Both methods require some finessing. The NPC won’t jump down if it is too far and in the first method the animation is already set so you need to use landing points that match.

As you can see in this project I’ve created an electrical panel and a toolbox for the first Combine Police to jump down onto. These are brush based and work out well for a project like this.

For the second Combine Police that makes use of info_node_hint entities I’ve created a group for the hints this NPC will use. This is to keep the NPC from getting distracted.

The first method works much better as the info_node_hint method can easily be interrupted by other events in your project.

Note.pngNote:The first Combine Police spawns with a point_template but not the second one. This is to illustrate how both methods can work either way. It is much more efficient to spawn your NPCs with templates when needed and then target them with the kill command once they are no longer needed. The template in this project could have handled both NPCs.

The first Combine Police

These are the setting for the first Combine Police.
