I'm stuck on increasing the jump height of the player.

 

Here's my code:

@SubscribeEvent
public void onJump(LivingEvent.LivingJumpEvent e) {
	if(!e.getEntityLiving().worldObj.isRemote && e.getEntityLiving() instanceof EntityPlayer) {
		EntityPlayer p = (EntityPlayer) e.getEntityLiving();
		PlayerStats stats = ScalaeCapabilities.getStats(p);

		if(stats.hasPerk("jump_height_1") || stats.hasPerk("jump_height_2")) {
			p.posY += 10D;

			System.out.println("HELLO");
		}
	}
}

 

I've tried using the *= operator and nothing happens. The message "HELLO" is being printed.

Try increasing the player's y velocity, instead of position. I believe that's how the potion effects works.

"motionY" field if I'm not mistaken.

motionY on the player needs to be applied on the client, because of how vanilla handles player input

why wont you just take a look at the jump boost effect? that's what i would do if i needed that....

that's why the forge source is there isnt it?
