Server-side anticheats monitor movement and packet anomalies, while static analysis with Leaf Mod Analyzer identifies hostile and unfair code before mods are loaded.

Combat Inventory Hotbar Auto-Swap

Q: How does Leaf Mod Analyzer detect Combat_Auto_Swap?

Leaf Mod Analyzer performs static analysis of JVM bytecode and decompiled AST structures matching Identifies SlotActionType.SWAP (field_7791) usage with ClientPlayerInteractionManager.clickSlot. in an isolated environment without executing untrusted JAR files.

💻 Mod Implementation (Dev Source / Mapped)

// Developer Source (Fabric / Yarn mappings)
public class AutoSwap {
    public static void quickSwap(MinecraftClient client, Item item) {
        int slot = findItem(client.player.getInventory(), item);
        if (slot != -1) {
            client.interactionManager.clickSlot(0, slot, client.player.getInventory().selectedSlot, SlotActionType.SWAP, client.player);
        }
    }
}
