Only allow if player has permission.

For my kitpvp plugin i am making a GUI that lists all kits. These kits will only be accessible by level. How do i make it if players don't have permission fortis.rank.2 and so on the glass for the ranks will turn back and if they do have the permission it will turn green and allow them?

 

Code:
If(p.haspermission("whateveryouwant"){

//if player has permission whateveryouwant
} else{
P.sendmessage("dont have permission");
Return true;
}

 

Yes i already know but would that still apply to changing a glass pane to either black (no permission) or green (has permission)

 

I would use this method.

Code:

boolean statement ? true result : false result;

In your terms

Code:

        ItemStack is = new ItemStack(Material.STAINED_GLASS_PANE);
        Colorable color = (Colorable) is.getData();
        color.setColor(p.hasPermission("your.permission") ? DyeColor.LIME : DyeColor.GRAY);

 

Line: 52
Colorablecolor=(Colorable)is.getData();

Check the permissions before opening the inventory for him. Then according to the permissions he has set some glass planes black, and some green.

 

I can't seem to do it!!!!!

Code:

    ItemStackrod=newItemStack(Material.STAINED_CLAY,1);

        ItemMeta rodmeta = rod.getItemMeta();

        rodmeta.setDisplayName(ChatColor.translateAlternateColorCodes('&',"&b&lRod God"));

        rodmeta.setLore(Arrays.asList(ChatColor.AQUA+"Get Speed 2 when you hold a rod!",ChatColor.GOLD+"REQUIRES LVL: 1",ChatColor.GRAY+"Broken"));

        rod.setItemMeta(rodmeta);

        if(cfg.getInt(p.getUniqueId() + "." + "rank") <= 2){
            MaterialData data = rod.getData();
            data.setData((byte) 5);
            p.updateInventory();
        }else{
            MaterialData data = rod.getData();
            data.setData((byte) 2);
            p.updateInventory();

        }

 

@SneakyBruh

the data will define the color

 

@SneakyBruh
1. You have put "ItemStackrod =newItemStack(Material.STAINED_CLAY,1);"
Its supposed to be:

Code:

ItemStack rod = new ItemStack(Material.STAINED_CLAY,1);

2. I do suggest making an array list instead of using Arrays.asList();

Code:

ArrayList<String> rodlore = new ArrayList<String>();

3. Doing the if statement will be totally wrong under it (Not trying to make you feel bad or anyone else for that matter):

Code:

if (cfg.getInt(p.getUniqueId()+".rank") <= 2) {
               // blah
} else {
               // blah
}

4. As @Caderape2 had said, use (short) instead of (byte) will work
