[REQ] Better Pistons

Hello bukkit community,
I dont know if this is possible but it would be grate if someone makes the pistons work like the ones from the piston mod (throw people and sand/gravel up in the air) I think the first feature should be easy but I dont know if it works with Sand / gravel.

King Regards

Yes.

 

That should be possible. actually...

 

Would anyone try it?

 

I'll try it in a little while.

Well, I just racked the bukkit code, and found "no existing code" that will let us enhance the pistons.

This will have to wait until they code in the API for pistons. For now, this project is "On Hold."

I support this.
Can't wait to see it.

 

Push. Piston API was added in rb 1000

 

@Klausar : Can't really say it was entirely added, it was a rudimentary (basic) piston support. I can "probably" get it to work with blocks. Players, I'll have to play around with it.

I should be able to get it up later today if I can find time.

 

Sand and gravel are more important than players.

 

That's good to know. I'll see what I can do about that when I wake up.

 

It's easy to launch a player into the air! My SuperJump plugin does it.
player.SetVelocity is your new friend!

 

@Bubby4j : Ah, but detecting when the player is pushed by a piston is not easy.

Edit in: In second thought, before I started coding I realized that you can't move individual "blocks" smoothly in a single direction without a client mod, so I will give up for now. I don't make client mods at the moment.

 

How about detect when any piston is activated, and then look through the players to check if they are on top of a top-facing piston?

 

@Bubby4j : then turning on pistons somewhere else when standing on top of an extracted piston would push the player in the air. rather... I think the guy wanted the blocks more than the player, and although I could probably code players (and entities) being tossed up like that, i am slightly inconvenienced on time now.

 

Is this back on with build 1000? I can't believe Notch left out the only real cool part of pistons... throwing things! I hate that guy so much...

 

Please Please make this work! this is what pistons need to be good again.

 

If someone else wants to attempt this they can. Right now, not only are there too many bugs with attempting it, there is not enough ability to even fully implement this (in my opinion)

 

I looked through the bukkit coding, and why is it not possible to use the mobile class and spawn it?

Code:

        World w = event.getPlayer().getWorld(); //temp
        org.bukkit.entity.FallingSand fs = w.spawn(event.getPlayer().getLocation(), org.bukkit.entity.FallingSand.class);
        fs.setVelocity(new Vector(0, -10, 0));

I already used it to spawn fireballs; why wouldn't it work with sand this way?

Plus, all there is to it is check if the block ontop of the piston is sand/gravel and turn this block into a moving entity. I believe it turns to gravel/sand on impact automatically.

Same counts for bouncing off mobile entities that are x distance away from the piston.

 

Could that push sand up in the air? I'm too tired to think at the moment.

Either way that would solve half the problem. Detecting PEOPLE being pushed is another issue. (btw... I should probably look more into entities huh. I'm a bit lazy on the entity part, good job on that)


If I can get enough sleep I'll see what I can do about sand/gravel when I wake up. Haven't been having too much luck, with plugins, recently.

 

You sure should, since there is an Entity class for all sorts of objects in the game:

Code:

        org.bukkit.entity.TNTPrimed.class;
        org.bukkit.entity.Player
        org.bukkit.entity.LivingEntity
        org.bukkit.entity.Creature

They should at least inherit SOME of the movement functions, although I never managed to make the Player class move using its velocity property. I believe the velocity gets updated elsewhere, using the onmove event in the background. Strange is, that if you set the velocity of an animal to 2+, they "teleport" (move too fast). This means it does affect something....

 

using "player" (from above: event.getPlayer()) you setVelocity on the player.

 

Any news?

 

@Klausar : Sorry Klaus, I haven't had any time to work/mess around with this feature. It honestly shouldn't be that hard though, unless the piston API refuses to allow it. If no one does it within a week or so, I'll work on it.

 

Bump, I'm very interested in having this. Maybe as a Config file for how high/far they launch?

 

damn, this one is the 3 today whit the same REQ-.-

 

@Marius A Winsjansen : You do realize this topic itself is a month old right?

No1 want to do this?

@Klausar
Actually, a similar plugin already exists: http://forums.bukkit.org/threads/23075/

 

Well it can launch players but no Sand or gravel
