Hello World! I'm talking about random numbers in Alice3. Random numbers can be used in many ways. One way is to play games, You can flip a coin or pick a random card from a deck. The other thing we can do with random numbers is to make movement seem more natural. For instance if someone is jumping up and down they're not going to jump exactly the same amount each time, so we could make that amount they jump a random number within some range that we want to jump. For this video, what we're going to do is just display some random numbers. I'm going to select Shapes/Text and then pick new TextModel, Make that kind of small so that we can see all the digits that are going to be displayed. Select edit code and we're going to select a variable, and make it a double, and name it randomNumber. We have to pick something for the initializer, but it doesn't matter what. and then say OK. We're going to change that to random and it says next double and range from 0 to 1. and we could change those values if you wanted to. I'm going to set the value for my text model to a custom text string, of nothing, a null string, and then add to that something, and that something is going to be the randomNumber. When we run our movie, each time we run it were going to see for random value, that is greater than zero but less than one. and you can see some of the values that were displayed by that code.
