Here’s an example used in an buyable (that I use for different currencies)

11: {  
title: “Buyable Example”,  
unlocked() { return true },  
cost(x) {  
let exp1 = new Decimal(1.2)  
let exp2 = new Decimal (1.1005)  
return new Decimal(2).mul(Decimal.pow(exp1, x)).mul(Decimal.pow(x , Decimal.pow(exp2 , x)))).floor()  
},  
display() {  
return “Cost: " + format(tmp[this.layer].buyables[this.id].cost) + " A-Points” + "  
Bought: " + getBuyableAmount(this.layer, this.id) + “  
Effect: Nothing” + format(buyableEffect(this.layer, this.id))  
},  
canAfford() {  
return player.A.points.gte(this.cost())  
},  
buy() {  
let cost = new Decimal (1)  
player.A.points = player.A.points.sub(this.cost().mul(cost))  
setBuyableAmount(this.layer, this.id, getBuyableAmount(this.layer, this.id).add(1))  
},  
effect(x) {  
let base1 = new Decimal(1.46)  
let base2 = x  
let expo = new Decimal(1.012)  
let eff = base1.pow(Decimal.pow(base2, expo)).times(buyableEffect(‘mE’, 14).pow(0.2))  
return eff  
},  
},

Not sure if it works since I wrote it in here instead of VSCode.

[Change Buy() & canAfford() to your conditions of currency :)] (Same with everything else in here)
