Class entity() { // there is obviously more code but i dont think if adding them will help val bodyInTheWorld: Body? = null // nulls mean that it will be initialised later, obviously } I need to set it to null because I need to do a
createThis.bodyInTheWorld = world!!.createBody(createThis.body) in main.kt. And that I don't have access to the world object of the main class inside my entity.kt class
class main : ApplicationAdapter() { private var batch: SpriteBatch? = null private var image: Texture? = null private var player: entity? = null private var camera: OrthographicCamera? = null private var world: World? = null private val entities = mutableListOf<entity>() fun createObject(createThis: entity) // will create reference or copy issues probably... { if(!entities.contains(createThis)) entities.add(createThis) createThis.bodyInTheWorld = world!!.createBody(createThis.body) var temporaryShape = PolygonShape() temporaryShape.setAsBox(50f, 1f) createThis.bodyInTheWorld.createFixture(temporaryShape, 1f) } I was about to write more code but I couldn't fix this damn thing: if I set it to var the last line will tell me that it requires an immutable argument.
Smart cast to 'Body!' is impossible, because 'createThis.bodyInTheWorld' is a mutable property that could have been changed by this time
And if I set it to val, the code doesn't let me do the main thing I want, which is to make that body exist in the world.
createThis.bodyInTheWorld = world!!.createBody(createThis.body) This time the problem is, by syntax and complexity, more reasonable at least, it tells me that I can only define bodyInTheWorld variable only once and that I already did that by setting it to null in entity.kt
I need help on this. This is the guide I used to implement box2d btw
