Method Detail

tryExecution

public boolean tryExecution()

Description copied from class: Command

Check and set marks to see whether this command conflicts with any other command.

First check whether the mark is already there. If it is our mark, then it is fine. If it is someone others mark, then we have a conflict. If there is no mark, just put the mark there.

With conflict there first find out which one is the stronger. If it is us, then we must override the mark. If it is not us, then we can't do what we wanted to.

There are also other kind of things that can conflict with a command. For example, if we are moving, someone or something can be in the way. To cope with conflicts you can also add new commands. In the case of previous example, we can for example add a new command to move the guy in front of us out of our way.

You should use setExecute() to tell whether the execution of the command is successful.

Overrides:
