Dynamicly changing Pickaxe Efficiency (MineSpeed)

I wanted to change the Efficiency of a tool dynamicly and mcreator doesent give you the option to do that yet(would be cool) so i made a little workaround.

Overriding the getDestroySpeed methode in the Itemclass of my in that case pickaxe:

public float MiningSpeed = 1f;

@override
public float getDestroySpeed(ItemStack itemstack, BlockState state){
	Player player = Minecraft.getInstance().player;
	if(player != null){
	return MiningSpeed;
	}
	return super.getDestroySpeed(itemstack, state);
}

public void setMiningSpeed(float miningspeed){
	MiningSpeed = miningspeed;
}

and then calling the setMiningSpeed methode from a procedure with the codesnipped:

Player player = (player) entity;

float miningspeed = (float)DoubleArgumentType.getDouble(arguments, "MiningSpeed") //put whatever you want here in my case its from a command with number parameter "MiningSpeed" for now. can be everykind of variable or number whatever.

YourItemNameItem yourItemNameItem = (YourItemNameItem) player.getMainHandItem().getItem();

yourItemNameItem.setMiningSpeed(miningspeed)

this seems to work fine. Im new to coding stuff so its probably a bit scuffed. if you have improvements please say so.

also im gonna try to do something similar so i can change the MiningLevel dynamically aswell.
 

edit: could i also just override the get tier methode?
