How To Center/Keep HUD Object in The same Place?

[Zipcord]

My x and y for drawing the rectangle is right above my health bar but it moves when i change my GUI and resolution. How to make it stay in the same place?

 

package studio.zipcord;

import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.Gui;
import net.minecraftforge.client.event.RenderGameOverlayEvent;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;


public class HudRenderer {
    
    
    @SubscribeEvent
    public void onRenderGameOverlay(RenderGameOverlayEvent.Post event) {
        if (event.type == RenderGameOverlayEvent.ElementType.ALL) {
            if (main.hideHealthBar) {
                drawRectangle(630, 860, 1000, 5, 0xFF0000FF); 
            }

        }
    }
    private void drawRectangle(int x, int y, int width, int height, int color) {
        Gui.drawRect(x, y, x + width, y + height, color);
    }
}
