Learning to code in Roblox Studio is quite fun. But can also present some challenges to the beginner who is just learning scripting techniques. This article will cover five ways coders can test and perform error checking in Roblox development. All of these methods will help identify errors in scripting, and one in particular will save you a lot of time as you learn to debug your code.

1. Studio Debugger

By default, Roblox Studio has a built-in debugger that allows the user to create breakpoints, where the user can pause the scripts to inspect them in real time. This tool also can keep track of variable values at each checkpoint, when the user turns on the "Add Watch" feature on the Script menu.

2. Command Bar

One tool that is available in both Studio and the Developer Console is the Command Bar. This tool allows the user to test any and every script command while the game is running in real time. This tool can also be found on the View menu in Roblox Studio.

3. Computer Log Files

Log files on your computer are created whenever a script runs or prints something, and keeps track of the effects of that script. Depending on whether you have a PC or Mac computer, your scripting log files can be found where the data for Roblox is housed. On PC this is found in the AppData folder (often a hidden folder), and on Mac is housed in the Library/Logs file folder. This is a useful tool if the user is comfortable moving around in the files on the computer, but would be considered a bit more advanced than other methods of debugging.

4. Studio Script Analysis Tool

Perhaps the easiest and most helpful method to check scripts in Roblox Studio is by using the built-in Script Analysis Tool. The tool can be opened as a side panel from the View menu. Not only can it find errors in your script and flag them as you write them, but this tool can also warn you about issues that could become a bug in your code and validate your code for proper syntax. Knowing at a glance if the scripts need indentation or need a variable are just some of the warnings that are flagged when using this tool.

5. Studio Output Window

From the View menu, open the Output Window to view all messages and errors that run while the game runs. The output can be customized by the user with filters, including warnings versus errors, errors by context (client, server), and level of detail provided to the user.

Try error checking in Roblox development tips

There are plenty of tools available to script writers in Roblox Studio, whether you prefer to view logs or watch the built-in debugging tools while you write your scripts. Once you identify errors, you can learn to code more efficiently as you learn proper syntax, coding language, and features specific to Lua, the scripting language used for Roblox Studio.
