تحضير

Install Hammer Addons. You can download it from هنا.

Make a simple map

Making the vactube mesh

Place

comp_vactube_spline

and connect them like a

keyframe_rope

Compile the map and see if it works and tubes are there, if it doesn’t. Check if your postcompiler.exe works.

Making the cube flow

This is optional

Place comp_vactube_start and rotate it how you like

Then place comp_vactube_junction and change the “يكتب” to whatever you want

Align it properly to match other junctions and/or start/end, or it won’t work and it will say “No destanation found for primary output”

Placing the end point

Place comp_vactube_end and align it properly to match the last junction

Placing the cube

Place comp_vactube_object where you want

Inside its properties type a group name and specify the model

Now go back to your comp_vactube_start and specify the same group inside it

Also you can specify the speed you want.
