Cannot attach Kotlin scripts

[SWRHARD]

When i'm trying to attach kotlin script (Simple.kt) to a node, i got errors and the field "Language" are not changed to Kotlin

Godot version: 4.0.3 stable

Hello ! In 4.0 you need to attach the .gdj file that is generated at compile time. See #441

[SWRHARD]

Hello! Okay, i read this topic, but still dont understand how to generate .gdj files from idea, i have Simple.kt file:

@RegisterClass class Simple: Spatial() { @RegisterFunction override fun _ready() { GD.print("Hello world!") } }

i build the project (./gradlew build) and gdj file has to appear? Thanks

Can you provide your gradle build script ?

[SWRHARD]

build.gradle.kts

  plugins {
      kotlin("jvm") version "1.7.20"
      id("com.utopia-rise.godot-kotlin-jvm") version "0.6.0-3.5.2"
  }

  group = "org.example"
  version = "1.0-SNAPSHOT"

  repositories {
      mavenCentral()
  }

  dependencies {
      testImplementation(kotlin("test"))
  }

  tasks.test {
      useJUnitPlatform()
  }

  tasks.withType<KotlinCompile> {
      kotlinOptions.jvmTarget = "1.8"
  }

You're using godot kotlin 0.6.0-3.5.2, which is built for godot 3.5.2. As we did not finished 4.0 work yet, you will need to build locally this repo (master branch) or use dependency substitution to test godot with 4.0

okay, thanks! probably i will use godot 3.5.2 now update: i downloaded 3.5.2 version, but still can't to open my Simple.kt file :/

You need godot with kotlin module: https://github.com/utopia-rise/godot-kotlin-jvm/releases

Yee now it works, thanks! But my script is not working now, i attached it to sprite node:

@RegisterClass
class Simple: Sprite() {        
          @RegisterFunction
          override fun _ready() {
              GD.print("I am ready!")
          }
      }

But the scene is closed immediately, i have only two rows in console, "I am ready" is not writing(:

--- Debugging process started ---
--- Debugging process stopped ---

If i remove my script, scene works)

0.5.2 was a broken build 0.6.2 should work without issues.
