[1.21] Config Equations

[SomewhatDamaged]

Describe the solution you'd like
I had a thought about a possibly better way to handle things like level-up equations and possibly death equations.

You could use String.format to basically build an equation and then evaluate it as the level-up/death equations.

So, for the exponential leveling curve in 1.20.1:
String levelFunction=String.format("250 * 1.104088404342588^(1.1 * %d)",level);
Or the linear one:
String levelFunction=String.format("250 + 500 * %d",level);
Then use javax.script.ScriptEngine to evaluate it and cache the value.
Then all the config would need is that string: "250 * 1.104088404342588^(1.1 * %d)"
Rather than the multiple variables needed, and the switch between leveling type.

Why is this feature needed
To make equations a little more friendly to edit and a lot more powerful.

Ah, more safe than eval. There's a java eval for math only posted over here, with a waived-rights license on it: https://stackoverflow.com/a/26227947/19846989
