Placing Custom Block Error

imutig

Hello! I have an issue when I try placing a custom block using the ItemsAdderAPI in my plugin.

Here is the code I use to place the block :

public void generateRandomBlock(Location randomLocation) { System.out.println("Generating block at " + randomLocation.toString()); CustomBlock.getInstance("iasurvival:cassiterite_ore").place(randomLocation); }

Here is the error I get :

java.lang.NullPointerException: Cannot invoke "dev.lone.itemsadder.api.CustomBlock.place(org.bukkit.Location)" because the return value of "dev.lone.itemsadder.api.CustomBlock.getInstance(String)" is null

Ok that's really weird; I don't understand.

Here's my code :

    public void generateRandomBlock(Location randomLocation) {
        System.out.println("Generating block at " + randomLocation.toString());
        CustomBlock customBlock = CustomBlock.getInstance("ruby_ore");
        if(customBlock != null)
        {
            customBlock.place(randomLocation);
        } else
        {
            System.out.println("Block not found");
        }

I promise I won't lie here : This worked at some point. I put the randomLocation at the center of the mine (because it's supposed to generate blocks inside a mine) and it worked.

Then, I changed the way coords are generated. NOTHING ELSE. And now it says "Block not found" when generating the block. I tried going back to the center of the mine, and it still stays Block not found… what am I missing ?
