Solved How can I make launch pads?

These launch pads allow players to step onto a block and get launched about 15 blocks high and 25 blocks as a distance. These pads allow people to jump across the map to make it easier than walking. How can I make these?

 

You need to set the velocity of the player when it steps on a plate, maybe you can see some good code in this topic;

Listen for PlayerInteractEvent, check if it is Action.PHYSICAL, see if the clicked block is a pressure plate, and use Vectors setting the Y and X/Z to get the distance, then multiply it.

 

xTrollxDudex not a pressure plate though. Can I change the block type?

 

Developerjohn
Sure, but you will need to use PlayerMoveEvent

 

xTrollxDudex k thnx

 

Which is highly frowned upon

Check every 1-2 blocks the player travels, not every time he moves his head.

 

I made a plugin about the launch pad before , I think you may need to follow this code :/

Code:java

 @EventHandler
public void onPlayerMove(PlayerMoveEvent e) {
if (e.getTo().getBlock().getRelative(BlockFace.DOWN).getType() == Material.REDSTONE_BLOCK) {
e.getPlayer().setVelocity(e.getPlayer().getLocation().getDirection().multiply(4));
e.getPlayer().setVelocity(new Vector(e.getPlayer().getVelocity().getX(), 1.0D, e.getPlayer().getVelocity().getZ()));
jumpers.add(e.getPlayer());

That code does not invole pressure plates like the hive , you can change the

Code:java

Material.REDSTONE_BLOCK

To something else :/
Edit: I have made one, heres the link : http://dev.bukkit.org/bukkit-plugins/playerboostpads/

 

ShearsSheep which part do I have to change the velocity on?

 

Code:java

e.getPlayer().setVelocity(e.getPlayer().getLocation().getDirection().multiply(4));

see the ().multiplay(4)); ?? You could change the 4 to any other number , but i recommend it not to be over 10. Correct me if i'm wrong. The "4" is the effect of the launch , the higher the number , the higher/faster it launches the player.

 

ShearsSheep ok thanks. Idk if your right about the 10 thing because I didn't know how to make launch pads, until you helped me. I'll have to look into that.

 

Anytime , if you need any help , buzz me in via skype: ShearsSheep

 

PlayerMoveEvent if called whenever a player's pitch, yaw, or coordinates change.

I realized that already... PlayerMoveEvent is often used in large plugins like WorldGuard, it is not frowned upon. What is frowned upon is cancelling it, perfect for someone you hate as their screen completely bugs out and they have to leave to prevent nausea. Again, you would check every 1-2 blocks the player moved.

 

just compare event.getTo() and event.getFrom(). if the X/Y/Z values all match, the player didnt really move.

 

If you're making multiple checks on PME with over a hundred players on a server, that's quite a lot of resources being used

 

SmellyPenguin
If statements have a very minute memory/proccessor footprint, you can't expect to lag a server using hundreds of if statements. If statements probably have such a small memory usage the probably can't even fall under "resource intensive".

 

You could have 1000 players on a home-hosted slow server all running around and this would still not produce any lag.

Code:java

 
@EventHandler
public void onPlayerMove(PlayerMoveEvent event) {
    if (event.getTo().getBlockX() == event.getFrom().getBlockX() &&
        event.getTo().getBlockY() == event.getFrom().getBlockY() &&
        event.getTo().getBlockZ() == event.getFrom().getBlockZ()) {
        return; // Player never actually moved.
    }
    // Player DID move, do stuffs here
}
 

 

Thanks for infos
