We have utils to find and swap items

I could not find any utils that tell me what inventory index the found items are in. We looked at this like 3 weeks ago. You couldn't find any either.

@Edouard127 so we merge?

just small things. Also, for single line if blocks, its often cleaner to omit the braces and keep them on the same line or at least the action after the check. Like this:

if (something) doSomething()
else if (something else) doSomethingElse()

+    tag = ModuleTag.MOVEMENT,
+) {
+    private var fireworkInteract by setting("Firework Interact", true, "Automatically start flying when right clicking fireworks")
+    private var fireworkInteractCancel by setting("Firework Interact Cancel", false, "Cancel block interactions while holding fireworks") { fireworkInteract }


Its annoying sometimes when you fly into a wall and try to use a firework for it to spam it on a block. Maybe this could be a general setting rather than an extension of fireworkInteract

You can just enable the Module

+    description = "Automatic takeoff with fireworks",
+    tag = ModuleTag.MOVEMENT,
+) {
+    private var fireworkInteract by setting("Firework Interact", true, "Automatically start flying when right clicking fireworks")


I would have used the name "Right Click Fly" instead of "Firework Interact"

src/main/kotlin/com/lambda/module/modules/movement/BetterFirework.kt

+                interaction.clickSlot(player.playerScreenHandler.syncId, swap, 0, SlotActionType.SWAP, mc.player)
+
+                if (player.getInventory().selectedSlot != 0) {
+                    player.networkHandler.sendPacket(UpdateSelectedSlotC2SPacket(0))


this should request the hotbar manager with keep ticks set to 0 for silent swap

src/main/kotlin/com/lambda/module/modules/movement/BetterFirework.kt

+    enum class TakeoffState {
+        NONE,
+        JUMPING,
+        START_FLYING


these should be in camel case

beanbag44

just one thing, aside from that i think its good

beanbag44 · 2025-11-01T23:10:26Z

src/main/kotlin/com/lambda/module/modules/movement/BetterFirework.kt

+    tag = ModuleTag.MOVEMENT,
+) {
+    private var fireworkInteract by setting("Right Click Fly", true, "Automatically start flying when right clicking fireworks").group(Group.General)
+    private var fireworkInteractCancel by setting("Right Click Cancel", false, "Cancel block interactions while holding fireworks") { fireworkInteract }.group(Group.General)


i meant that this shouldn't be dependent on right click fly to be a feature. This should be its own option, separate from firework interact
