Same as a procedure do block, but calling this procedure returns a result.Īfter creating this procedure, a call block that needs to be plugged in will be created. You use the call block to invoke the procedure. When you create a procedure, App Inventor automatically generates a call block and places it in the Procedures drawer. Java kewords cannot be used as procedure names.
App Inventor will automatically rename the associated call blocks to match. You can rename a procedure at any time while you are building the app, by changing the label in the block. App Inventor will not let you define two procedures on the same screen with the same name. Procedure names in an app must be unique. When you create a new procedure block, App Inventor chooses a unique name automatically. If you click the blue plus sign, you can drag additional arguments into the procedure. If the procedure has arguments, you specify the arguments by using the block’s mutator button. You can then use the sequence of blocks repeatedly by calling the procedure. In computer science, a procedure also might be called a function or a method.Ĭollects a sequence of blocks together into a group. Instead of having to keep putting together the same long sequence of blocks, you can create a procedure and just call the procedure block whenever you want your sequence of blocks to run.
