Adding a delayed task to a plugin
We will now add a warp delay to the Warper plugin. This will require players to stand still after running the warp or home commands. If they move too much, the warp task will be canceled and they will not be teleported. This will prevent players from teleporting when someone is attacking them or they are falling to their death.
If you haven't already, add a variable of warpDelay in the main class. This is given in the following line of code:
static int warpDelay = 5; //in seconds
This time will be in seconds. We will multiply it by 20 later in the code to calculate the number of ticks by which we wish to delay the task.
We will also need to keep track of the player who is in the process of warping so that we can check whether they are moving. Add another variable of the current warpers. This will be a HashMap so that we can keep track of which players are warping and the tasks that will be run to teleport them. That way, if a specific player moves, we...
