about the alert message

[borische1322]

do we need to pause all thread when a message pops up?, because for me when a lost message pops up the other robot kept moving and when the other robot won there are repeated message pop up. and if we need to pause all thread when a lost message pops up, can you give use some hint? coz how to pause a thread when the alert message is executed by the application thread?

Either to pause other threads or not is fine. See #6 #53 #62.

I cannot tell how to let other threads pause. This is unfair to other students. In general, you need some kind of "signal" to let other threads know when they should pause and when to resume.

i can think of one way of doing so without using static variables but that would require modifying/adding variables in other classes like gamestate or gameboard, is that allowed?

Yes you can add instance fields in classes. It is much safer than static variables.

I am doomed. So, several tests can modify a shared variable at same time?

Well, I can see many of you use static variables. I will change the execution of tests to sequential mode. Each test will be executed after previous one finishes. However, static variables are still dangerous since functionalities will be tested many times and the static variables will not be reset in the tests.

Thank you very very very much.

My comment is that tests for concurrent programs are often executed concurrently.

FYI, I manually do concurrent execution of multiple players in each test case to test concurrency bugs.

Thanks Wuqi.

Just to confirm- we now only need to ensure thread and player concurrency, no need to worry about test concurrency (i.e. possible concurrent MainGamePane) right?

[Troublor]

Yeah, there wont be two game running at the same time

Thanks a lot
