Reverse push?

[Hipshot]

Is it possible to turn a jump pad upside down, or in some other way speed up a players fall. When I tried this, the trigger_push and target_push wouldn't work... they work perfect in a normal fashion.

So.... a pull then?

I could think of super ugly hack...

Trigger_Multiple and a caulk brush. As player falls, hits trigger, caulk brush crashes down pushing the player down.

Totally useless for a practical use in anything meant to be playable though.

Set the 'speed' key of the target_push to something like 2000 or more. It defaults to 1000 and since the default gravity is 800 u/s, you won't notice much of a difference.

[Silicone_Milk]

Or that.

Maybe I don't recall correctly, but trigger_push or target_push won't work if they are pointing downwards...?

[maz0r]

You're right spookmineer. The info_position must be at least one unit above the trigger brush or the push will not work at all. You can only try to make a fast nearly horizontal push followed by a curve diverting the player downwards.

[Hipshot]

Yes - seems they don't.
Never tried it before, looking at what I wanted to do - doesn't seem so good after all anyway... gimmick effect I probably should distance myself from these days.

After some poking around in the source... the game takes the square root of the height somewhere but that doesn't work for negative values (i.e. down) so it fails and bails. I should've remembered because this bug is fixed in the modlet I'm working on.

[Silicone_Milk]

Why take the square root of the height? Wouldn't it be cheaper to just add a float value to the entity's velocity?

[Hipshot]

I gota give it to you ^misantropia^ - it's nice having a coder around. I pick up stuff from you about the engine that I never would have else.

[^misantropia^]

@Silicone_Milk: it's to take gravity into consideration, or you wouldn't hit the target. If you're curious, it's in AimAtTarget() in game/g_trigger.c.

@Hipshot: glad to have been of help =)

[Silicone_Milk]

Thanks I was actually looking at that a few minutes ago. I was going to take a whack at altering it to push down as well as up.

"As player falls, hits trigger, caulk brush crashes down pushing the player down."

This wont leave you with any extra velocity after it's finished pushing you.

[Silicone_Milk]

Make it last for the duration of the fall?

[neoplan]

Hipshot: The DeFRaG mod has this feature. You can create a trigger_push_velocity where you can define if velocity is added to your speed or taken away (you can set these values separate for x y z direction or combine them).

Btw.: Is it possible to calculate the hight of the player after triggering a jumppad? I can remember that there was a feature in Q3Radiant, where you could display the flight path of a jumppad.

Testing Jump and Launch Pads

Jumppads can also be tested. Type the following on the Quake III Arena console, before loading your map:

/set bot_maxdebugpolys 1024
/set bot_visualizejumppads 1
/set bot_forcereachability 1

Now load the map. A counter will be shown and goes from 0% to 100%. When the counter has reached 100% type /set r_debugSurface 2 on the console. For every jumppad the default arc of travel (without using air control) will be visualized.

Possibly a viable hack would be to place slick on a downward slope from the jump pad, forcing the player down.
