I´ve tried the following code for making a block pull away the players, but it also works with the other entitys.

How can i make it work only in players?.

Thx

public class trampa extends Block {

public trampa(int id, Material Material) {
	super(id, Material);
}
    /**
     * Returns a bounding box from the pool of bounding boxes (this means this box can change after the pool has been
     * cleared to be reused)
     */
    public AxisAlignedBB getCollisionBoundingBoxFromPool(World par1World, int par2, int par3, int par4)
    {
        float f = 0.125F;
        return AxisAlignedBB.getAABBPool().getAABB((double)par2, (double)par3, (double)par4, (double)(par2 + 1), (double)((float)(par3 + 1) - f), (double)(par4 + 1));
    }

    /**
     * Triggered whenever an entity collides with this block (enters into the block). Args: world, x, y, z, entity
     */
    public void onEntityCollidedWithBlock(World par1World, int par2, int par3, int par4, Entity par5EntityPlayer)
    {
        par5EntityPlayer.motionX *= -10D;
        par5EntityPlayer.motionZ *= -10D;
    }
}

Hi

 

you could try

 

if (par5EntityPlayer instanceof EntityPlayer) {
        par5EntityPlayer.motionX *= -10D;
        par5EntityPlayer.motionZ *= -10D;
}

 

see here for more background information on Entity inheritance hierarchy...
