KorGE 1.12.8.0: Huge Optimizations!

Image
By soywiz


There is a new version of KorGE available now!

This version includes a lot of optimizations done to make all the targets faster, specially on Kotlin/Native.

We have rewritten the view's components system to be much faster and we have done tons of optimizations to reduce overhead of Kotlin/Native.

Before this version, the 10.000 sprites sample Nico Emig did, was terribly slow on Kotlin/Native. After profiling a bit we found a few places worth optimizing, and with a few changes in all the libraries, we got it working much faster. It is still not as fast as the JVM counterpart, but much closer than before.

Also a few versions ago, the Kotlin/JS optimization for instance checkings stopped from being applied due to a slight change in the output of the kotlin.js runtime. This version enables it again, making the JS target much faster than before.

After the profiling, we noticed that moving the mouse in the 10K sample caused the game from pause for a long time. This was the components system trying to propagate the mouse event to all those views. We have done a lots of optimizations here, and now that pause has totally gone away.

So far, this is the fastest version of KorGE to the date! Go ahead and try it. Just use 1.12.8.0 as your korge-gradle-plugin version.

KorGE Tutorial - Writing 2048 game. Step 1 - Views

By
In the previous step we have created and configured a KorGE project for our game. In this step, we'll discuss KorGE's views and their positioning. We will also fill our stage with static elements using views, such as Graphics , Container , RoundRect , Text and Image . At the end of this step we will have the following result: So let's start! Views and containers View structure in KorGE is based on two types of elements: views and containers. A container is a view that can have other views as children. During rendering, KorGE goes through the elements of the root container (the game scene) and draws them in the order they're added to the view structure. The element added first will be covered by the other element added after it and overlapping it: Each view has a size ( width and height ) and a position ( x and y ). Width and height  determine the size of the rectangle bounding this view, x and y  determine its position inside the parent container. Main sizes Befor
