Introduction

So, we are going to create rotating stand with portalgun shooting portals.

Prepare models

You will need:

prop_dynamic -- models/props/pedestal_base_reference.mdl -- name: stand_bottom_model prop_dynamic -- models/props/pedestal_center_reference.mdl -- name: stand_top_model Just create and name them, we will move them after next step

Prepare brushes

Create:

32 to 32 square, height 4 -- nodraw texture 4 to 32 sq, height 55 -- nodraw texture

Moving

Illustration 1.

Move stand_bottom_model where you want to have the stand, that small doors on it have to be under ground. Then move stand_top_model above stand_bottom_model, as on picture //soon// . Center 1st brush, that 32x32, with stand_top_model, Z axis to half of stand_top_model (approximately). And move 2nd brush as on picture.

PortalGun

Create new entity, weapon_portalgun and name it weapon_portalgun. Move it exactly to top of stand_top_model, a front part of portalgun has to be on left when you’re loking on stand_top_model from that part with blue display.

Logic

Make entity logic_timer named timer_stand and set interval to 5 sec. Make sure that initial state is on. Now go to outputs and write:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnTimer	stand_func_rotating	Start	<none>	0.00	No
	OnTimer	stand_func_rotating	Stop	<none>	3.00	No
	OnTimer	weapon_portalgun	FirePortal1	<none>	3.00	No

Select 32x32 brush and tie it to entity func_rotating. Name: stand_func_rotating | Friction: 0 | Max Rotation Speed: 30 | In Flags, unmark Start ON.
