This feature is available in most courses, barring the legacy Cyber Robotics 101 (Desert theme)
Ever wanted to look around from a bird's eye view? Well, if you're in Cyber Robotics 102 or The CoderZ Adventure courses, you have that power!
At the bottom-left corner of the simulation pane, you will find a window showing a bird's-eye view of the scene. Click it to switch to Explore Mode, then scroll down to zoom out and scroll up to zoom in. Move around by holding down the right mouse key and dragging.
The button in the bottom-right corner opens a toolbar which offers several useful features:
Note: not all features are enabled in all courses.
Distance Measuring Tool
Use this awesome feature to discover the distance between objects! For example, the distance between the robot and a container:
Once you know the distance your robot has to drive, use this information in your code.
Note: the distance in Explore Mode is measured in meters. If you are using a block that uses centimeters, don't forget to make that 1:100 conversion!
Angle Measuring Tool
Figure out angles easily with the handy Angle feature! Here's how to use it:
- Click on the scene floor where the vertex (point) of the angle you are measuring is located, and hold down your mouse key.
- Drag your mouse forward along the robot's trajectory (as though the robot is driving forward). A marker will appear. Release the mouse key.
- Move your mouse over the scene to create the angle, and see its value in the Angle panel!
Once you know your angle, use this information in your code.
Drive the robot around using your keyboard arrow keys, no code necessary! Just click this icon and explore the scene yourself! (Keep in mind, Manual Control might not be available in all courses, and if it is, most missions cannot be completed in Manual Control mode)
Restore Last Position
This tool allows you to turn back time, in a manner of speaking. Press it up to 3 times to make the robot jump back to its previous position! The 'position' in question is determined by the Blockly code: each block is one step or position further.
Time Scale (Fast-Forward)
This tool allows you to run the simulation at twice or at four times the normal speed. This can be useful for missions which involve long stretches of driving, or if you want to get past the first few blocks of your code quickly before slowing back to normal speed and debugging a specific part of the mission.
Clicking this button lowers the graphics quality of the Simulation, thus freeing up computer-power for rendering the simulation. The higher FPS utilized in Low Quality mode allows for more consistent behavior, including the robot's movement and its various sensor readings. Users who experience inconsistency in the simulation are encouraged to use Low Quality mode to boost their computer's power, especially when using older and/or weaker computers or networks.
Note: every time you restart a mission, reset a simulation, refresh your browser, or move on to a different mission, the Simulation will revert to the default High Quality mode, so you will have to click the button again to reduce it to Low Quality.
