bounce/jump pad question

[MonoXideAtWork]

I'm trying to create a jump pad for my latest map, and I can't seem to get it to function how I like.

I have a cylindrical brush textured with tools/trigger, and tied to a trigger_push.

The brush is the full height of the jump I'd like the player to make.
push direction is "up" and push force is 1000u/s
Technically, it works, but not how I expect it to. I would like it to function like the pads at the entrances to the bases in ff_aardvark, where you touch it and you're off. At the moment, it requires a jump to get going, like the fan shaft in ff_bases. Can anyone point me in the right direction? Thanks.

heh, put a sign that says JUMP!!

You could use SetVelocity rather than a trigger_push for precision pushing.

------------------------------------------
-- jump triggers
------------------------------------------
base_jump = trigger_ff_script:new({ pushx = 0, pushy = 0, pushz = 0 })

-- push people when they touch the trigger
function base_jump:ontouch( trigger_entity )
	if IsPlayer( trigger_entity ) then
		local player = CastToPlayer( trigger_entity )
		
		player:SetVelocity( Vector( self.pushx, self.pushy, self.pushz ) )
	end
end

-- up push
jump_up = base_jump:new({ pushx = 0, pushy = 0, pushz = 1000 })

You could alter it to make it work similarily to a trigger_push as well, or just put one of these at the very bottom and lower the push so that it just gets you off the ground and then the trigger_push takes over.

SetVelocity ftw...

Used a func_door to raise my person off the ground, at which point the push takes over!

[Cyanyde]

Put it slightly below ground.
The player will drop onto it at which point they will get "pushed" in the direction you want.

That's an interesting idea... I may have to try that!

What if I wanted to add a sound to this so everytime I hit the jumppad it creates the sound?

I would like to use the sound Doors.Move14 which I think comes from hl-2.

Would it work if In the trigger I just put this: or does it need precached?

base_jump = trigger_ff_script:new({ pushx = 0, pushy = 0, pushz = 0, touchsound = "Doors.Move14", })

[squeek.]

It'd probably need to be precached and it'd need a line in base_jump:ontouch to actually play the sound. But, you're most likely better off using an ambient_generic entity in the map and then making it play the sound with Lua using OutputEvent, though, as BroadCastSound plays the sound universally and doesn't factor in a player's distance from the event itself.

To play an ambient generic from Lua, use:

OutputEvent( "entity_name", "PlaySound" )

To add this to the trigger code while making it easy to have jump triggers with different sounds, you would do this:

------------------------------------------
-- jump triggers
------------------------------------------
base_jump = trigger_ff_script:new({ pushx = 0, pushy = 0, pushz = 0, sound_entname="base_jump_sound" })

-- push people when they touch the trigger
function base_jump:ontouch( trigger_entity )
	if IsPlayer( trigger_entity ) then
		local player = CastToPlayer( trigger_entity )
		
		player:SetVelocity( Vector( self.pushx, self.pushy, self.pushz ) )
		OutputEvent( self.sound_entname, "PlaySound" )
	end
end

-- up push
jump_up = base_jump:new({ pushx = 0, pushy = 0, pushz = 1000, sound_entname="jump_up_sound" })
jump_up_alt = base_jump:new({ pushx = 0, pushy = 0, pushz = 1000, sound_entname="jump_up_sound2"})
