question - ConfigurableMessages

Hi, I need advice. My plugin receives an error message (for someone). And I would like to ask if I have something bad in code. Or it could be poor compatibility with some plugins.

Here is the error message that I received from one user:

Classes which shows the error message:
ConfMsfStringSetings: https://github.com/Sickagp/Configur...leMessages/Settings/ConfMsfStringSetings.java
ConfigurableMessagesListener: https://github.com/Sickagp/Configur...bleMessages/ConfigurableMessagesListener.java

Thank you for any help

 

When you are creating the "str" variable, you are passing the null "plugin" variable inside the constructor. Instantiate it after you instantiate the "plugin" variable.

 

If I understand you well, so it should look something like this?

Code:

    ConfigurableMessages plugin;
    public ConfigurableMessagesListener(ConfigurableMessages instance) {
        plugin = instance;
    }
    ConfMsfBooleanSetings s = new ConfMsfBooleanSetings(this.plugin);
    ConfMsfStringSetings str = new ConfMsfStringSetings(this.plugin);
    ScoreBoardManager score = new ScoreBoardManager(this.plugin);
