I see that your plugin has a maximum of 20 XP for each level, while mine has a different amount for each one, starting from 100 XP for the first level up to 20.000 XP for the last one. Am I right about the first one?
If I'm correct, the amount of XP that will be transfered should be equal to "20 * (level - 1) + current XP".
According to this, if for example a player has 15 XP and he is on level 7, he should receive 135 XP in my plugin (20 * (7 - 1) + 15).
I assume you haven't changed the cvars in the plugin and they are using the values set in the .sma file. If you did change them, please give me your values.
// Nevermind, I can retreive the cvar value in the plugin itself. Just tell me if everything I said is right and I will make the transfer plugin for you.
