Vacuum Tube

Vacuum Tube (or Vac-tube)

The Vacuum Tube (or Vac-tube) is used within the Aperture Science facility to transport testing apparatus.

How to create one

Making basic shape First start of making the basic shape of your vac-tube.

Vacuum-Tube example

Here is a list of useful models: vacum_entrance_a.mdl vacum_flange_a.mdl vactube_connector.mdl Making items inside First, start by making path_tracks. Don't forget to turn on teleport to this path in first path track.

Path_track example

Now create 2 prop_dynamic_overrides, and 3 brushes in the same place. Convert two of them to func_rotating and the 3rd one to func_tracktrain. Parent prop_dynamic to func_rotatating, func_rotating to 2nd func_rotating, and then to func_tracktrain. Set track train speed to 450-600, height above track to 0 and distance between the wheels to 0. Now go to flags and check allow roll (z-rot). Now open both of func_rotatings and in flags check x axis in the first and y axis in 2nd. Set rotating speed to 150.

Now set 2 different models to prop_dynamics_overrides. Create logic_auto and give it outputs. Output Name Activator Via this input On Map Spawn prop_dynamic_override1 turn off On Map Spawn prop_dynamic_override2 turn off

Create logic_case. Add outputs Output Name Activator Via this input OnCase1 prop_dynamic_override1 turn on OnCase1 prop_dynamic_override2 turn off OnCase2 prop_dynamic_override1 turn off OnCase2 prop_dynamic_override2 turn on

Now in the last path_track of your tube create outputs: Output Name Activator Via this input OnPass LogicCase PickRandome

Putting Gel Inside

Create an info_particle_system entity, set 'Start Active' to yes. Set the 'Particle System Name' to 'blob_curve' (Conversion Gel) or 'blob_curve_blue' (Repulsion Gel) or 'blob_curve_orange' (Propulsion Gel). Create an 'info_target' entity and put it somewhere inside the tube, then go to your info_particle_system and set control_point_1 as info_target. If you want your tube to have gel sounds, create ambient_generic inside the tube. Set the sound name to world.gelflowherolp, volume to 10 and max audible distance to 1250.
