Faith Plate

Faith plates or catapults are jump pads in Portal 2. They can fling objects (like turrets and cubes) and players.

Creation

1) Make a prop_dynamic:

Property Name	Value
World Model	"models/props/faith_plate.mdl" or "models/props/faith_plate_128.mdl"
Name	"catapult_model_1" (you can change it, but dont forget to change it in all inputs.)
Collision	Not Solid
Disable Shadows	Yes

2) Make a info_target

Property Name	Value
Name	catapult_target_1

• The catapult will launch you onto that target.

3) Make a trigger_catapult with trigger texture:

Property Name	Value
Name	catapult_trigger_1
Launch Direction	"-90 0 0" If you want to fly up
Player speed	Try random for your length of pit, 750 is better
Physics speed	This for flinging props. I have +150 to Player speed (900).
Apply Angular impulse	True
Launch target	catapult_target_1
Use Threshold Check	Set to NO for Faith Plate model.

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnCatapulted	catapult_model_1	SetAnimation	(angled, fast or straigthup)	0.00	No

4) Make a ambient_generic:

Property Name	Value
Name	catapult_sound_1
Sound Name	Metal_SeafloorCar.BulletImpact
SourceEntityName	catapult_model_1 (the name of the Faith Plate model)

Flags	Value
Is NOT Looped	Yes
Start Silent	Yes

5) Make a func_clip_vphysics whitn trigger texture in space under faith plate model,or objects will fall down.

6) Make a block whit "player clip" texture in space under faith plate model,or you will fall down.

7) Also,dont forget to add info_placement_helper to the ceiling,its easier to fly through.

Tips

You can use the trigger_catapult anywhere you expect the player to slingshot. For example, you may place a portal on a wall angled upwards and sling out of that. For greater control on where the player lands use a trigger_catapult.

To make sure the catapult doesn't fling you when you just walk into it, set the thresholds. In the trigger_catapult settings:

Property Name	Value
Lower threshold	This is a percentage, 0 to 1, of the player speed you set.
Upper threshold	Same as above but for the upper limit.
UseThresholdCheck	'YES' to use threshold, 'NO' to always catapult.

For example, say you set the catapult to fling the player at 500 units/s. Lower threshold 0.1 means the player must travel at least 10% of that; 50 units/s. Upper threshold 0.5 means the player cannot travel faster than 50% of that; 250 units/s. As long as the player speed is between these limits the trigger_catapult will enable.
