The new challenge player is a new and improved version of the current 'Challenge Player' with a focus on accessibility and usability. This is the first step in creating a seamless and consistent user experience when playing challenges in any play mode. 

This feature is currently in preview and only available in Tournaments, Assessments and Courses, to enable it please read How to Enable Preview Features

Now let's go through all the new features:

• Information about the vulnerability 
• Only show files marked as vulnerable 
• Rule out answers
• Wrong answers/solutions are excluded through retries 
• Improved markings in the code
• Open files in separate tabs 

Information about the vulnerability 

This feature aims to enhance the overall learning experience as it provides more information about the vulnerability the challenge is about along with a learning video.

Only show files marked as vulnerable

You can toggle the "Highlighted files only"  to show only files marked as vulnerable in the file tree.

All code blocks marked as vulnerable will be listed under the 'Code blocks' section along with the status of each one of them (refer to improved markings in the code)

Rule out answers

This feature allows you to rule out answers that you are confident are incorrect, making it easier for you to keep track of what you have ruled out and what you still need to consider. 

Note: You can undo this action by clicking the same button.

Wrong answers/solutions are excluded in retries 

When you retry a challenge, previously submitted incorrect answers or solutions will be marked with an X so you don't accidentally submit the same answer/solution twice. 

Note: Hints will rule out wrong options that haven't been already eliminated.

Improved Markings in the code 

Additional meaningful markings in the challenge screen to help you keep track of your progress; each code block is marked with an icon that indicates its status. 

• Unticked checkbox: unselected code block that can be submitted as an answer.
• Ticked checkbox: a code block selected in order to be submitted as an answer.
•  Unticked-disabled checkbox: unselected code block that has been ruled out from being a correct answer. 
• Cross: a code block that was previously submitted as an answer, but it's not the correct answer.
• Lightbulb: a code block contributing to the vulnerability 
• Unlocked padlock: a code block that has been eliminated after using a hint.
• Check Mark: a code block that was submitted as an answer and is correct.

Open files in separate tabs 

You can now open files in separate tabs which allows you to easily switch between them.
