Example JSON file:
[
{
"discordId": "9273927302020",
"characters": [
{
"name": "Rare_Character",
"value": 1
},
{
"name": "Ultra_Rare_Character",
"value": 1
}
]
}
]
Let's just say for example I ran this simple gacha and got 4 characters:
let i = 1
var picks = []
while(i <= 4){
const { pick } = gacha.simple(alpha)
picks.push(pick)
i++
}
Now, picks has an array like this:
[
{
"name": "Common_Character"
},
{
"name": "Ultra_Rare_Character"
},
{
"name": "Common_Character"
},
{
"name": "Rare_Character"
}
]
How do I increment the value in My Example JSON file based on the name from what I got in my gacha results picks while ignoring the Common_Character and only passing those Rare and Ultra_Rare ones?
I've tried filtering them like this:
var filter = picks.filter(t => t.name === 'Rare_Character' || t.name === 'Ultra_Rare_Character')
Now I don't know how to increase those values in my JSON file and what if in the gacha results I got two Rare_Characters or Ultra_Rare_Character
I'm using fs to read my JSON file but I just don't know the logic to increase values
const src = [

"discordId": "9273927302020",

}
];
const gacha = [

},
{

},
{
"name": "Common_Character"
},
{
"name": "Rare_Character"
}
];
const updateValues = (src, gacha) => {
const gachaSums = gacha.reduce((collector, current) => {
collector[current.name] = (collector[current.name] | 0) + 1;
return collector;
}, {});
src.characters.forEach(srcChar => {
gachaSums[srcChar.name] = srcChar.value + (gachaSums[srcChar.name] | 0);
});
src.characters = Object.entries(gachaSums).map(([key, value]) =>
({ name: key, value: value })
);
return src;
}
console.log(updateValues(src[0], gacha));Maybe this version could help
