I believe the problem is that the garbage collection doesn't ever kick in when switching scenes. So as you continue to switch between scenes, the number of allocated objects increase, thus resulting in a OOM.

Personally, I don't understand much about how garbage collection works for a multiplatform project/JVM myself so will need to do some research.

Also it seems like System.gc() is not available for a multiplatform project, so you can't activate garbage collection yourself.

got it to work and I don't know how

You can set the orientation on gradle:

https://github.com/korlibs/korge-plugins/blob/master/korge-gradle-plugin/src/main/kotlin/com/soywiz/korge/gradle/KorgeExtension.kt#L230

// build.gradle korge { orientation = Orientation.PORTRAIT fullscreen = true }

And on your fun main IIRC:

fun main() = Korge(fullscreen = true) { }

I have the same issue. I was able to get my package to download via

repositories { // https://stackoverflow.com/questions/59413364/upgrading-from-gradle-5-1-1-to-6-0-1-breaks-kotlin-multiplatform-build jcenter { metadataSources { gradleMetadata() mavenPom() } } jcenter() } dependencies { add("commonMainApi", "com.github.glwithu06.semver:semver:1.0.1") }

but I cannot resolve it in my code, it's like it's not on the classpath
I also tried using

plugins { java } dependencies { implementation("com.github.glwithu06.semver:semver:1.0.1") }

but does not even add it to my external dependencies (although it's downloaded and it's in my modules-2 gradle cache folder along with sources jar, main jar and pom.xml

any ideas?

@soywiz said in High CPU usage when game is idle:

This is not currently implemented, but could be implemented in a future version. Both not flipping the buffer and adjusting the fps.

Thank you @soywiz . I created https://github.com/korlibs/korge-next/issues/176 for this.

I also created the issue to allow downloading KorGe artifacts via JCenter: https://github.com/korlibs/korge-next/issues/121

I also noticed that centerOn stopped working (at least in some cases) after some KotGe library upgrade.
And I easily changed this to the manually calculated positioning ( position(x, y) )
E.g. in https://github.com/andstatus/game2048/blob/master/src/commonMain/kotlin/org/andstatus/game2048/presenter/Block.kt I changed:

centerOn(this@graphics)

to

position(cellSize / 2, cellSize / 2)

@Saiful-Anwar Thank you for the contribution!
I only had to fix it a bit 🙂 and add wrapping for e.g. Chinese texts,
and it works well for my Help screen.

ended up doing this.:

var down = false onDown { down = true GlobalScope.launch { delay(500) if (down) { // do the thing } } } onUp { down = false }

That's called "anchor" on KorGE. image.anchor(0.5, 0.5) should do the trick

My final output of the Kotlin multiplatform project is

JS (node module) library JVM lib (jar).

All good with projects which using my JVM jar as the pom XML have the korlibs (JVM jars) from maven. The issue is with JS projects using my js library.
So, to answer your question, YES, I am consuming it from a NodeJS project, which expects the js version of these libraries to present in the npm registry.

I can see a question already there for klock w.r.t this.
