Green value, you know, is like 200 and it’s blue value. Is Europe so notice? The syntax here it’s an object, and this should be in quotes it’s a bunch of key value, pairs, property name value. So what all the flower has a name. It’S sunflower, a flower has a red value. 255. All of these is a list of these properties. All separated by commas, the last one has no comma after it and then a close curly bracket. Now, as I go through more and more examples, your goal to see that these this file can get enormous ly more complex. It can have arrays built into it. It kind of objects, nested in other objects and I’m, so excited to look at all of those scenarios, but right now, I’m, going to keep it very, very simple, but I’ll reason why I’m mentioning the syntax so specifically, is one comma out of place. One quote out of place your program, won’t work and often you’re not going to get such a great error message. So you know we have to sort of like think about and look at like how you can deal with that. But one way of dealing with it is just be really really careful as you kind of enter your data into a JSON file. So you know I pretend reading my flower encyclopedia. I found all this information I’m going to format the data, so I can use it. So I’ve come back over here.
How am i doing on time? Seven minutes you’re watching a video for seven minutes, it’s, really quite impressive on the internet and I’m going to go over here to this plus and I’m going to hit. That plus, which is going to allow me to add a new file and the new file, is going to be called flower I’m. I was saying flowers because ultimately, I kind of want this file to be a list of different kinds of flowers, but right now, I’m kind of being simple, so I’m, just going to say flower, JSON and I’m going to do exactly what I said: I’m gon na Say: name: son, oops name, sunflower, our is 255 G is 200 and B. Is a B is zero? Now, so you can see here now I have this file called flower. Json and it’s got the data in it. Now I hopefully did that correctly, but let’s say you’re, not sure if you did it correctly well, there happens there’s a lot of these tools online there’s, a lot of tools online that allow you to validate or check the syntax of a JSON file to make sure It’S valid so I’m going to very quickly just copy paste this and go to Chrome I’m, going to open up Chrome and I’m going to go to JSON 4 I’m going to Google JSON format, err and just click. On the first thing that comes up I’m, going to paste the data into this box and I’m going to click a process right here which is going to validate and check my JSON and it says valid and you can even see it’s sort of like syntax, highlighted And did some things with it and we might look at this later some other ways you could do this, but this I’ll try to include a link to this particular tool in the either an annotation or in the comments below so so.
So, in other words, I’m asked to load that data and that data it’s gon na take some time it’s on the hard drive the gnomes in the computer have to go and like dig into the hard drive and find and pull it back up a draw boom Is happening immediately, so what I need to do is I need to enforce there’s a couple things. I need to enforce that the data is loaded before I start trying to draw with the data and a quick way to do that, which is ultimately not the way that I’m going to show you in all of the videos, but at least we’re getting started. A quick way of doing that is using the preload function, so function preload. You know everything is event based, and you know the events that are happening here in this particular sketch is preload flower dot, JSON uh, oh reload, it’s, the first thing that runs and in everything that in preload, when it finish everything that’s loaded in preload when it Finishes loading setup that runs and then draw runs, so this is a way of guaranteeing that by the time we get to draw that data will be in that particular variable. I hope this works now and you can see it does and you can see. I have my text of the sunflower there on the screen, so a mr. sort of wraps up a kind of very basic start of ok there’s, a low JSON function for what is JSON.
You know I’m sure you can think of something more interesting than just what I’ve done here and something else that I’ll mention which I’ll show in the beginning of the next video is. There is a wonderful github repository what’s good hub – oh my god, what’s good that’s, a tie. I need to have make a video about that, but I don’t know whoops I’m in the wrong place here I’m trying to open something it’s gif oak romesco. I was trying to open this is a github repository maintained by a Darius Kazemi. Hopefully I pronounced his name correctly and what it is is it’s a whole lot of JSON files, all about different topics that people have manually made or pull together from different sources and contributed so let’s, say you’re interested in art. I could click here isms, and this is like a big list of all sorts of like kinds of isms like electrician, lumen, ISM, lirikl extraction ISM. So anyway, I encourage you up and pull it link another place you can do if you’re like don’t, want to feel like typing out your own dataset is go to this repository. Look at the different JSON files. There try to copy paste one of them into your code, see if you can get access to it and I’m going to look at one from this particular set. I won about birds that I have in mind that look at in another example. In other context, then you know this is perhaps a for another time, but you might think about contributing back if you’ve made the most wonderful flowers.
Is there a flowers one in here? Oh it’s, like a flower code, oh yeah, there’s, fireworks. Flowers! Look at this! Ah, this is, I needed this so here’s a list of flowers anyway, up you might make your own data set and contribute it back to this place for other people to use as well. So thanks for watching in the next video I’m going to pull another JSON file is a bit more complexity to it, because that’s going to help us overall we’re on this train, we’re going to get to this point of like we don’t, have this local file we’re.
