Crusher

In Portal 2, Crushers are Panels with spikes. Like panels, they are attached to robotic arms. However, directly behind the robotic arm is a massive piston which drives the crusher.

Creating Crushers

1. Create a prop_dynamic entity with the following settings:

Property Name	Value
World Model	models/anim_wp/cursher/crusher.mdl
Name	crusher1
Collision	Not Solid
Hold animation?	Yes

2. Create a 128x64x192 block brush around the spikes on the model. Tie it to a func_brush entity with the following settings:

Property Name	Value
Name	crusher1_brush
Parent	crusher1

3. Create a 200x112x192 block brush around the previous brush. Tie it to a trigger_hurt entity with the following settings:

Property Name	Value
Name	crusher1_trigger_hurt
Parent	crusher1
Damage	1000
Damage Cap	1000
Damage Type	CRUSH

4. Create a 200x96x192 block brush around the trigger_hurt brush. Tie it to a trigger_portal_cleanser entity with the following settings:

Property Name	Value
Name	crusher1_trigger_hurt
Parent	crusher1
Visible	No

and the following outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnDissolve	(your dropper's trigger's name)	Trigger		0.00	No

5. Create a logic_auto entity and set up the outputs as follows:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnMapSpawn	crusher1_brush	SetParentAttachmentMaintainOffset	base_attach	0.05	No
	OnMapSpawn	crusher1_trigger_hurt	SetParentAttachmentMaintainOffset	base_attach	0.05	No

6. Create a logic_relay with the following settings:

Property Name	Value
Name	crusher1_logic_relay_crush

with the following outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnTrigger	crusher1	SetAnimation	smash_in	0.00	No
	OnTrigger	crusher1_trigger_hurt	Enable		0.00	No
	OnTrigger	crusher1_math_counter	SetValue	0	0.00	No

7. Create a logic_relay with the following settings:

Property Name	Value
Name	crusher1_logic_relay_uncrush

with the following outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnTrigger	crusher1	SetAnimation	smash_out	0.00	No
	OnTrigger	crusher1_trigger_hurt	Disable		0.00	No
	OnTrigger	crusher1_math_counter	SetValue	1	0.00	No

8. Create a logic_compare with the following settings:

Property Name	Value
Name	crusher1_logic_compare
Initial Value	0
Compare Value	1

and the following outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnLessThan	crusher1_logic_relay_crush	CancelPending		0.00	No
	OnLessThan	crusher1_logic_relay_crush	Disable		0.00	No

9. Create a math_counter with the following settings:

Property Name	Value
Name	crusher1_math_counter
Maximum Legal Value	1

and the following outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OutValue	crusher1_logic_compare	SetValue		0.00	No

10. Create a func_instance_io_proxy entity with the following settings:^[Why?]

Property Name	Value
Name	crusher1_proxy_crush

and the following outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnProxyRelay1	crusher1_logic_relay_crush	Trigger		0.00	No
	OnProxyRelay2	crusher1_logic_relay_uncrush	Trigger		0.00	No
	OnProxyRelay3	crusher1_logic_compare	Compare		0.00	No

11. Create a logic_relay entity with the following settings:

Property Name	Value
Name	crusher1_proxy_crush

and the following outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnProxyRelay1	crusher1_logic_relay_crush	Trigger		0.00	No
	OnProxyRelay2	crusher1_logic_relay_uncrush	Trigger		0.00	No
	OnProxyRelay3	crusher1_logic_compare	Compare		0.00	No

12. Set up triggers to open or close the crusher by triggering the proxy relays on crusher1_proxy_crush. Use crusher1_logic_compare to get the state of the crusher.
