[1.7.10] Help I'm stuck. Literally!

I've added a pavement block to my mod, and theres 1 huge bug with it.

The pavement block is a half block in which makes you go faster when you run on it. It's amazing and my friends love it. Except for one huge problem. There's a random chance that you get STUCK IN the pavement. You can't move your head, jump, or walk, and it looks like youre a phone on vibrate or having a seizure. And it starts depleting your food bar at an alarming rate. Even in creative mod you get stuck and have to continue to try to fly over and over until you break free. Survival players have to log out and log back in. It seems to be more prominent when bunny-hopping

public void onEntityCollidedWithBlock(World par1World, int par2, int par3, int par4, Entity par5Entity)
    {
        par5Entity.motionX *= 1.15D;
        par5Entity.motionZ *= 1.15D;
    }

any ideas?

See how soul sand does it.

that is how soulsand does it. i just made it go higher instead of lower

This is more than likely a problem with the way minecraft handles the players movement and lag probably has something to do as well. I would just try to make it a full-sized block.

Try giving the speedboost only serverside, not clientside.

Also imagine this. Your speed is 1 you move at 1 block per tick. Suddenly your speed is 1.5 moving 1.5 blocks per tick. Client promply adjusts and puts you in the wall/block on the side. Server says. Hey. You cant be in a wall. Get out. Client says my speed is 1.5 im gonna put player to far again and so a tug o war happens between client and server.

how would i go about making it server only?

how would i go about making it server only?

World#isRemote, it is true if it is the client's world.

i don't think i did it right... it doesn't look like im getting stuck anymore unless it just hasnt happened yet, but the internal server is nonresponsive. mobs dont move, and i cant punch them, and i cant pick up items

 public void onEntityCollidedWithBlock(World world, int par2, int par3, int par4, Entity par5Entity)
    {
    	if(world.isRemote = true)
    	{
        par5Entity.motionX *= 1.15D;
        par5Entity.motionZ *= 1.15D;
    	}
    }

false makes it crash on contact

Uh oh. That is noobish code, learn Java. Use (!world.isRemote)

well now it doesnt work at all

What do you mean doesn't work at all?

Basic Java

You said:

	if(world.isRemote = true)

You need to have two equal signs to compare two objects.

So it should be:

if(world.isRemote == true)

Uh oh. That is noobish code, learn Java. Use (!world.isRemote)
