So I'm trying to create a lighter, so On and Off. Here is my code

import net.minecraftforge.server.console.TerminalHandler;
import net.minecraft.commands.CommandSourceStack;

import java.nio.file.Path;

public class FlashLight extends Item {
public FlashLight(Properties pProperties) {
super(pProperties);
}
boolean FlashSwitch = false;
Vec3 pos1 = null;
Vec3 pos2 = null;
Direction Dir = null;
boolean ON = false;

@Override
public InteractionResult useOn(UseOnContext pContext) {
if (!pContext.getLevel().isClientSide) {
Boolean ShiftDown = pContext.isSecondaryUseActive();
Player player = pContext.getPlayer();
MinecraftServer server = pContext.getPlayer().getServer();
if (FlashSwitch) {
pos1 = pContext.getPlayer().getEyePosition();
FlashSwitch = !FlashSwitch;
player.displayClientMessage(Component.literal("§cOff"),true);
ON = false;
} else if (!FlashSwitch) {
FlashSwitch = !FlashSwitch;
player.displayClientMessage(Component.literal("§eOn"),true);
ON = true;

while (ON) {
Dir = pContext.getPlayer().getDirection();
if (Dir.equals(Direction.NORTH)){
player.displayClientMessage(Component.literal("§eNORTH"),true);
} else if (Dir.equals(Direction.EAST)){
player.displayClientMessage(Component.literal("§eEAST"),true);
} else if (Dir.equals(Direction.SOUTH)){
player.displayClientMessage(Component.literal("§eSOUTH"),true);
} else if (Dir.equals(Direction.WEST)){
player.displayClientMessage(Component.literal("§eWEST"),true);
}
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
throw new RuntimeException(e);
}


}
}
}
return InteractionResult.SUCCESS;
}
}
This barely works, the switch between on and off doesnt work, and when i turn directions it doesnt display the direction im facing, please help ASAP.

boolean FlashSwitch = false;

Blocks and items are singletons, this value is shared across all "instances" of your item. You have to store this data in an ItemStack's capability.

That's not really the problem, i have a separate item with the exact same on and off switch and it works perfectly fine. The problem is something with the loop i presume, as without it the switch works perfectly fine. I'll explain what i need the item to do, first off blocks cant be transparent (or at-least that's what i think) so i thought of setting the block behind the player to a black block with a light level of like 6 or something. I need to detect the direction the player is facing at all times so i can set the block behind them to a light block.

Nevermind i just figured out that i can make transparent blocks with AirBlock, that saves alot of time.
