I am making an image edit command, I am trying to find the last image in a channel but when I run it it says that url1 is undefined code below.
const url1 = msg.channel.lastMessage.attachments.url;
You need to get the first attachment, as message.attachments is an array:
msg.channel.messages.fetch().then((messages) => {
const lastMessage = messages.sort((a, b) => b.createdTimestamp - a.createdTimestamp).filter((m) => m.attachments.size > 0).first();
const url1 = lastMessage.attachments[0].url;
});

I'm working on semi-gacha bot command where you can pull characters and so on. I want to display the characters image after the user pulls and here is where I get stuck, it just doesn't display anything and I found what looked like the answer on here, but it didn't help, as I would get the same result and I don't get any errors, so I don't know what exactly is wrong. I have tried printing out the result of MessageAttachment first:
const attachment = new Discord.MessageAttachment('./chars/1.Jakku.png', '1.Jakku.png');
console.log(attachment);
and I get: undefined, anybody has any ideas of what am I doing wrong? And yes, I have discord.js library imported.
Relevant part of the code:
collector.on('collect', reaction => {
//new embd
const newEmbd = new Discord.MessageEmbed();
// gacha logic
if (reaction.emoji.name === '✅') {
const values = Object.values(chars);
const randomChar = values[parseInt(Math.floor(Math.random()*values.length))];
const attachment = new Discord.MessageAttachment('./chars/1.Jakku.png', '1.Jakku.png');
const charData = randomChar.split('.');
newEmbd
.setTitle(`You pulled: ${charData[1]}!`)
.setColor('YELLOW')
.attachFiles(attachment)
.setImage(`attachment://1.Jakku.png`);
embdReact.edit(newEmbd);
pulled = true;
} else if (reaction.emoji.name === '❌') {
newEmbd
.setTitle('Time for gacha!')
.setColor('YELLOW')
.addFields(
{ name: 'Result:', value: 'You decided against pulling' }
);
embdReact.edit(newEmbd);
};
});
You need to use the correct syntax for attaching files as per this guide
const exampleEmbed = new Discord.MessageEmbed()
.setTitle('Some title')
.attachFiles(['./chars/1.Jakku.png'])
message.channel.send(exampleEmbed);
I am trying to put a cursed image command in my discord.js bot but it keeps coming up with this error
got('https://www.reddit.com/r/madlads/random/.json').then(response => {
^
ReferenceError: got is not defined
Here is the code
if(command === "cursed") {
got('https://www.reddit.com/r/cursedimages/random/.json').then(response => {
let content = JSON.parse(response.body);
var image = content[0].data.children[0].data.url;
let permalink = content[0].data.children[0].data.permalink;
let memeUrl = `https://reddit.com${permalink}`;
let memeImage = content[0].data.children[0].data.url;
let memeTitle = content[0].data.children[0].data.title;
let memeUpvotes = content[0].data.children[0].data.ups;
let memeNumComments = content[0].data.children[0].data.num_comments;
const cursedembed = new Discord.MessageEmbed()
.setColor('RANDOM')
.setTitle(content[0].data.children[0].data.title)
.setURL(`${memeUrl}`)
.setImage(image)
.setFooter(`👍 ${memeUpvotes} 💬 ${memeNumComments}`)
.setTimestamp()
message.channel.send(cursedembed);
});
}
Since you don't have node-fetch as one of your packages, you won't be able to use the fetch function. In order to use this package, you'll have to follow three steps.
Install node-fetch. This can be done by running npm i node-fetch in your project directory.
Import node-fetch into your code. This can be done by having const fetch = require('node-fetch'); at the top of your code file, similar to your discord.js import.
Replace got with fetch.
After that, you should be able to use fetch in order to download web content and post reddit content on discord.
Making a command to take a random photo of a waifu in this case, and posting it in the channel
Code here:
if (command === 'waifu') {
const waifu = new Discord.MessageEmbed()
got('https://waifu.pics/api/sfw/waifu').then(response => {
let content = JSON.parse(response.body);
let waifuUrl = content[0].data.children[0].data.url;
let waifuImage = content[0].data.children[0].data.url;
waifu.setImage(`${waifuImage}`)
waifu.setURL(`${waifuUrl}`)
waifu.setColor('#ffb9f4')
waifu.setFooter(`Requested by ${message.author.user}`)
waifu.setTimestamp()
waifu.setAuthor(`waifu.pics`, `https://waifu.pics/`)
message.channel.send(waifu)
});
};
The API should be correct. After a few small changes, I tried console logging the JSON and it did output the correct thing. But when running the code in discord, it outputted a TypeError: Cannot read property 'data' of undefined error. I cannot seem to figure out the problem
if (command === 'waifu') {
const waifu = new Discord.MessageEmbed()
get('https://waifu.pics/api/sfw/waifu').then(response => {
let content = response.body;
let waifuUrl = content.url;
let waifuImage = content.url;
waifu.setImage(`${waifuImage}`)
waifu.setURL(`${waifuUrl}`)
waifu.setColor('#ffb9f4')
waifu.setFooter(`Requested by ${message.author.username}`)
waifu.setTimestamp()
waifu.setAuthor(`waifu.pics`, `https://waifu.pics/`)
message.channel.send(waifu)
});
};
You thought a little bit complicated ^^ You had something with children and data, although the API just gives an URL. You don't even have to parse it. And you have used the function got(), which you have to replace with get().
I fixed your code just copy it from above.
Hi ! I Need To Get A User Tag Using His Id In Sharding
I tried This Code But Doesn't Work :
let tag = await client.shard.broadcastEval(`this.users.get("id").tag`)
Any One Can Help Me Please!
Try this:
const user = (await client.shard.broadcastEval('this.users.cache.get("id")')).find(u => u)
if (user) {
let tag = user.tag
// do something with the tag
} else {
// the user wasn't found
}
Hey I've been building out a full-stack tinder app using react native + firebase auth/storage/realtimedb.
Everything has been going great so far but I've ran into an issue a few days ago and I don't know what's wrong with it.
I get back the correct uri of the image and pass it in as parameters to my uploadImage function and convert that to a blob. It uploads a file to firebase storage but it's not my image. This is what gets uploaded:
Image that is getting uploaded.
Weird things going on in the file description of my 'image'
The first things I notice is when I upload the image and look at the description of the supposed image I see that the size is 600,000 bytes which is strange because when I upload the pictures manually through the firebase storage console they are a few megabytes.
The second thing is the image preview is not working.
editAvi = async () => {
console.log('wtf')
await Permissions.askAsync(Permissions.CAMERA_ROLL);
const { cancelled, uri } = await ImagePicker.launchImageLibraryAsync({
allowsEditing: true,
});
if (!cancelled) {
this.setState({ image: uri });
}
console.log('The image is' + this.state.image)
};
uploadImage = async (uri, imageName) => {
// Create file metadata including the content type
var metadata = {
contentType: 'image/jpeg',
}
// Points to the root reference
var storageRef = firebase.storage().ref();
// Points to 'images'
const response = await fetch(uri);
const blob = await response.blob();
var ref = storageRef.child('images/' + this.state.currentID);
ref.put(uri, metadata);
console.log('This is the blob: ' + blob)
}
I've been researching this extensively for two days and have asked about it multiple times in a web development discord I'm in and I still can't fix it.
Please help me fix this! This is one of the last things I need to get this app done. :)
Found this question when I was also searching for an answer. I was able to solve this following the recommendation from a Github issue https://github.com/expo/expo/issues/2402#issuecomment-443726662
The main idea is to replace
const response = await fetch(uri);
const blob = await response.blob();
var ref = storageRef.child('images/' + this.state.currentID);
ref.put(uri, metadata);
with
const blob = await new Promise((resolve, reject) => {
const xhr = new XMLHttpRequest();
xhr.onload = () => {
resolve(xhr.response);
};
xhr.onerror = (e) => {
reject(new TypeError("Network request failed"));
};
xhr.responseType = "blob";
xhr.open("GET", uri, true);
xhr.send(null);
});
var ref = storageRef.child('images/' + this.state.currentID);
ref.put(blob, metadata);
Fetch in know to have a problem in ReacNative when using Expo.
Hope this solves it.
Found this question when I was searching around for a solution to the exact same issue. I fixed it after about 12 hours of trial and error by adding 'application/octet-stream;BASE64' a the type when creating the blob (using rn-fetch-blob).
Blob.build(data, { type: 'application/octet-stream;BASE64' });
Not sure if that's the method you're using to create the blob, but if so, using that as the type fixed the issue for me.
