How to force players to bounce

Archive: 14 posts


Many people have asked how I force the players to bounce in my level SlamBall (Click here (http://www.youtube.com/watch?v=vL7o5zAbjxw&feature=player_embedded) if you don't know what I'm talking about).

It is incredibly simple to achieve this effect. Anyone who has ever changed piston settings should be able to do it in seconds.

First, press pause.
Now use two pistons (P) to connect some Dark Matter (DM) to any other material (M).

So it looks like this:



MMMMMMM
P P
P P
P P
DMDMDMDM


1) Set both pistons to stiff
2) The minimum and maximum length of both pistons should be identical
3) Set one of the pistons to backwards
4) Set the speed to 0.1 in both cases

Un-pause. If you've done it right you should see no movement. If you do see some movement, check whether the minimum and maximum length is identical.

Next, do get a decent bouncing effect the distance between minimum and maximum length should at least be 4.

The longer the distance the higher the player will bounce.

---------

Problems:

a) Be warned that the "bouncyness" is sometimes weaker in play mode than it is in create mode, so be sure to check that.
b) All bouncing platforms can randomly stop working. This happens very rarely but you should nonetheless save regularly
c) Up-side-down platform can start moving.
d) You may notice that the platforms extent randomly (even into other objects). This so far hasn't broken anything for me, but don't blame me if it does in your level. :-)

-------

Hint: Anything not glued down will bounce. If that doesn't give you an idea for a survival challenge I can't help you.

Very cool! Isn't this similar to the "high jump" glitch?2010-01-23 13:16:00

Yes, quite similar. In fact I tried to build the high jump platform when I stumbled upon this.
The difference between two is that you don't need to press X to jump in this case. Which also means that you can make the player jump at your will, for instance to simulate the force of an impact if you want to go down the comedic route.

I just checked out your level to see this in action i must say its a nice little invention you have there and i would like to see how people could implement this in actual levels.2010-01-23 14:06:00

Hey i just thought you could turn it on or off as well by attaching a switch to the pistons (i know obvious but cool)2010-01-23 14:21:00

Yes, I ran into this when experimenting with high jumps. Maybe I mentioned it there, maybe not.

Anyway, bottom line: pistons are freaky! You can also make a wall you can pass through in only one direction, and a floor you sink into, but not completely. Put the latter on glass makes a water effect, but that's not very useful with real water out.

Yet another glitch i'll have to try.

It's a good thing you posted this because, sad to say, I probably wouldn't have thought of this.

Does this still work if the platform is on different angles? Some glitches i've worked with do get affected by the angle they're on.

It's been a while, but I think you can tilt the platform without affecting the glitch.2010-02-18 10:31:00

Sorry, late reply. Yeah, you can do that. That's how the balls bounce around at the end.
Upside down works too, but that can be a bit unreliable.

Me and bakscratch used this idea for one of the sections in Tricky's Temple Trials although it isn't particularly dangerous as we made it very obvious how to avoid it. It's worth having a look at though to see how it can be incorporated into a level without being too obtrusive as an obvious glitch.2010-02-22 22:26:00

Oh, have to play that level. Curious how people used it in real levels. I only used a little bit in "Just hatched!" so far aside from Slamball.

By the way, the level is copyable should anyone not manage to get the effect themselves and need to have a closer look.
