I think we discussed that on slack/discord already.
No ECS provided by the engine, but some people talked about that stuff via chat, so not sure if someone will work on a ECS engine.
Regarding to shaders: Shaders on KorGE are usually applied via filters, and created using a DSL for that. Please, check this link: https://github.com/korlibs/korge/blob/16aac42d6cf0e4eed19e088e12b73282661cf0f4/korge/src/commonMain/kotlin/com/soywiz/korge/view/filter/WaveFilter.kt#L31-L40

It is not straightforward. But you can read all the frames of the GIF and great a SpriteAnimation. Thought with a fixed frameTime even if the GIF has different frame times. You could also implement the animation image changing yourself manually. In the case is it enough for you to have a fixed frame time:

import com.soywiz.korge.*
import com.soywiz.korge.view.*
import com.soywiz.korim.bitmap.*
import com.soywiz.korim.color.*
import com.soywiz.korim.format.*
import com.soywiz.korio.file.std.*

suspend fun main() = Korge(width = 512, height = 512, bgcolor = Colors["#2b2b2b"]) {
	val frames = resourcesVfs["ed3002fb3b703f38807ddb7da020169d.gif"].readBitmapImageData(GIF).frames
	val frameTime = frames.first().time
	val animation = SpriteAnimation(frames.map { it.bitmap.slice() }, frameTime)
	val sprite = sprite(animation)
	sprite.playAnimationLooped(animation)
}

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) {
}

@Yuri-Volkov said in High CPU usage when game is idle:

@soywiz Could you give us any clue on possible ways to control graphic engine energy / CPU consumption / maximum frame rate ?

Can you create a feature request here?: https://github.com/korlibs/korge-next/issues/new

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

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

May I ask you your use-case? Are you consuming them from a language other than Kotlin? Why can't you consume them from the official maven repositories?

Unfortunately at this point, it is super experimental and more a proof of concept. @dhakehurst is making some contributions in korge-next related to KorGE3D: https://github.com/korlibs/korge-next/pull/23 but since that's a contribution I'm not sure how far that will reach on KorGE 2.0. The official plan is to work on the 3D part on KorGE 3.0 but since 2.0 is not released yet, it is a bit early for that

Right now, your best bet is to use the prompt method available on the gameWindow and the views instance.

https://github.com/korlibs/korgw/blob/e6aebe811a6a7b9c252ca3d82a3480859c8df34f/korgw/src/commonMain/kotlin/com/soywiz/korgw/GameWindow.kt#L22-L30

Acts like the javascript one: opens a dialog requesting a string.

On KorGE 2.0 we might add support for native textfields over the game window

The same way as the other properties. Colors and angles are specially handled here: https://github.com/korlibs/korge/blob/16aac42d6cf0e4eed19e088e12b73282661cf0f4/korge/src/commonMain/kotlin/com/soywiz/korge/tween/tween.kt#L242-L248

The way for doing that is:

view.tween(view::colorMul[Colors.RED, Colors.BLUE])
view.tween(view::rotation[180.degrees])

Also note that in addition to views you can interpolate any other property just using the [...] syntax.
The view from view.tween is the view that will register an updater, and as long as that view is on the stage, it will interpolate the properties on each frame.

I'm afraid we don't have that yet. We don't have too much resources, so we are focusing on the code. But any contribution in that direction will be awesome.

There is a sample with websocket client/server here:
https://github.com/mmo-poc/mmo-poc

I think gamepad is not supported on windows JVM.
Just created this issue for that: https://github.com/korlibs/korge-next/issues/29
