talium

Talium is a library that aims to simplify creating GUIs and its components in minecraft

Position/Size

one thing to note is that every position and size is in percent based on the screen and gui scale, it attempts to fit properly regardless of resolution (though falling short in some cases).

the size and position are relative to the parent so for example if you do x = 17 while it has a parent (meaning you either did addChild or parent = component) it will use the parent's position as a base and then add that into the equation

example

component1 = background(x = 10%)

component2 = main(x = 15%, parent = background)

then component2 will be x = 10% + 15% then be calculated into pixels (although it is calculated into pixels earlier on but for the sake of keeping this a bit simpler lets just imagine it does this)

example (docs coming soon probably)

first we create a background component which will be the root parent

private val background = UIRect(0.0, 0.0, 100.0, 100.0)

then we can start creating mutliple components inside of that root component that will be displayed (you must set the parent to the background one or call addChild inside it)

private val main = UIRect(17.5, 17.5, 65.0, 65.0, parent = background).apply {
  setColor(java.awt.Color.GREEN)
}

inside your Screen you should override these methods so that the components know what's going on (might have a UIScreen class in the future that does this for you)

    override fun extractRenderState(graphics: GuiGraphicsExtractor, mouseX: Int, mouseY: Int, a: Float) {
        super.extractRenderState(graphics, mouseX, mouseY, a)
        background.draw()
    }

    override fun charTyped(characterEvent: CharacterEvent): Boolean {
        background.handleCharType(characterEvent.codepoint, characterEvent.codepointAsString(), -1)
        return super.charTyped(characterEvent)
    }

    override fun keyPressed(keyEvent: KeyEvent): Boolean {
        background.handleKeyInput(keyEvent.key, keyEvent.scancode)
        return super.keyPressed(keyEvent)
    }

annd your first gui with talium is done.
