I’m beginning to learn how to develop for Vassal. I want to do a very simple thing using code: have a button that as soon as I press it will show a buffered image 300x300 with the number 1, which will stay on the map screen for 2 seconds, change into another image showing the number 2 and vanish, after 2 extra seconds, like counting.
I have gone through classes such as Map and Board to research their methods, but I’m really not sure how to approach the problem. I appreciate it if someone can point me to some documentation explaining the use of those classes other than the javadoc for vassal, or, at least, point me the classes which I must research for tackling this particular problem.
If that is the extent of your requirement, then the simplest way to handle this is probably to develop a Sleep(ms) Beanshell function.
You can do everything else with standard Vassal. E.g. have an invisible counter on the map that has the 1 and the 2 as layers, Then you can just drive it via a GKC initiated trigger. You can force the call to the Sleep(2000); function by creating a Dynamic Property and have Key Commands that set its value to {Sleep(2000)};
Forget that suggestion. It does not work at all. Swing repaints when it want to, not when you want to
Have a look at how the CounterDetailViewer works. It does a similar sort of thing (though much more complex), but basically, when something sets it off, it draws and maintains an image over the screen for a while.
The other option would be to build a custom trait to do it.
