Small issues before releasing on jpro.one

[FlorianKirmaier]

Hi @AlmasB

I've got some notes about the project:

• To Work as a JPro, it must be possible, to instantiate the application multiple times. Currently, I get the following exception when starting the application twice:

java.lang.IllegalStateException: Logger already configured
        at com.almasb.sslogger.Logger$Companion.configure(Logger.kt:29)
        at com.almasb.sslogger.Logger.configure(Logger.kt)
        at com.almasb.fxgl.app.GameApplication.initLogger(GameApplication.java:123)
        at com.almasb.fxgl.app.GameApplication.customLaunch(GameApplication.java:82)

I thinks that's something you have to fix inside of FXGL.

• Is it possible to skip the first intro? It currently doesn't perform very well. What are you using in it, which might cause the performance issue?
• This demo is good as a HelloWorld, because the code is quite short, but for the demo-page I think something a bit more complex would work better.

Hi @FlorianKirmaier

Many thanks for this.

1. I will carefully consider multiple instantiations, as it is not allowed by design in FXGL. By far this is the most difficult fix.

2. Yes, though I would rather fix the performance issue. I'll have a look at it. Behind it all, there is a lot of small ImageView objects, perhaps they are the bottleneck. Will let you know after I've done some playing.

3. We've got a couple of interesting-looking demos. Once the above fixes are known, I can start looking at that.
