Playing as a teacher in Worst Class Ever isn’t just about chasing students around the classroom. You also have access to special traps that can help you catch students when they’re making mischief. These include surveillance cameras and a radio, both of which give you useful information about what students are doing.
However, you can’t use these traps whenever you want. You first need to earn trap uses by letting students make enough Mischief during the class. Once you have a use available, you can activate either a camera or the radio to monitor student activity.
In this guide, I’ll explain how teacher traps work, how to earn trap uses, what surveillance cameras detect, and how the radio helps you track students making suspicious sounds.
Worst Class Ever Teacher Traps Guide – Cameras, Radio
Teachers have access to two special mechanisms:
- Surveillance Cameras: Monitor classroom activity and trigger an alarm when they detect certain student actions.
- Radio: Helps the teacher locate students who make specific sounds while performing mischievous activities.
Only the teacher can activate these mechanisms, and they can only be switched on during the Class phase.
Each activation consumes one trap use, so you’ll need to manage your available uses carefully.
How to Earn Trap Uses
Teachers earn trap uses as students increase the class’s Mischief total.
Under the default room rules, you receive one trap use at each of these milestones:
- 25% of the Mischief target: First trap use.
- 50% of the Mischief target: Second trap use.
- 75% of the Mischief target: Third trap use.
The host can change these milestones using the Trick Progress for Mechanisms room rule.
This setting moves the Mischief points required for the first trap use. The second and third milestones are calculated at two and three times the first milestone respectively.
Any trap-use milestones above 100% of the Mischief target are ignored.
You can also save your available uses because they stack. However, all remaining trap uses disappear when the class ends.
Important: If the host sets Enable Traps to No, the teacher won’t receive any trap uses.
Surveillance Cameras
Surveillance cameras allow teachers to monitor students without constantly following them around.
Once activated using the Enable option, a camera remains active for the rest of the class. It checks for suspicious student activity every 0.5 seconds and triggers an alarm when it detects a player-controlled student performing certain actions.
Camera Locations
The number of cameras depends on the classroom:
- Regular classrooms: 2 surveillance cameras per classroom.
- Dormitory: 4 surveillance cameras.
Look for the cameras mounted on the classroom walls.
Camera Detection Range and Movement
Each surveillance camera has the following characteristics:
- Sweep range: -75° to 75°.
- Turn speed: 20° per second.
- Pause at each end: 5 seconds.
- Field of view: 30°.
- Detection range: 12 metres.
- Alarm duration: 5 seconds.
The cameras rotate back and forth to monitor their surroundings. When they spot a player student doing something suspicious, they raise an alarm.
What Can Surveillance Cameras Detect?
Cameras can detect several actions performed by player-controlled students.
Holding Items
A camera can catch a student holding an item in their hands, with three exceptions:
- Pen
- Book
- Plunger
Holding other items can trigger the camera alarm.
Chewing Bubble Gum
Chewing Bubble Gum without having a balloon ready can also trigger the camera.
Playing Computer Games
If a player student is playing a game on a computer, the surveillance camera can detect it.
Keep these actions in mind if you’re trying to avoid being spotted while playing as a student.
Radio
The radio is the second mechanism available to teachers. Unlike surveillance cameras, it doesn’t directly detect what students are holding or doing. Instead, it helps identify students through the sounds they make.
Every classroom has one radio.
How to Activate the Radio
The teacher can activate the radio by approaching it and selecting Enable.
You must be within 2 metres of the radio to switch it on.
Once activated, no other player can use it. The radio remains active for the rest of the class, and only the teacher who activated it receives its tracking information.
What Sounds Can the Radio Detect?
The radio identifies player students making certain mischievous sounds.
These include:
- Bubble Gum: When a bubble bursts.
- Eating: When a student finishes eating a snack.
- Hot Pot: When a student eats cooked pieces.
- Phone: When a phone rings inside a drawer and is being used.
- Computer Games: When a player student is playing a game.
Whenever one of these sounds is detected, the teacher sees an arrow pointing towards the student who made it.
The arrow tracks the student’s latest sound for 1 second, helping the teacher identify where the noise came from.
Teacher Trap Room Rules
Two room rules directly affect how the teacher’s mechanisms work.
Trick Progress for Mechanisms
This setting controls how much Mischief students need to generate before the teacher earns trap uses.
Changing it affects the first milestone, while the second and third milestones are set at two and three times the first.
Enable Traps
This setting determines whether the teacher can earn trap uses.
- Yes: The teacher can earn and spend trap uses normally.
- No: The teacher receives no trap uses.
If you’re hosting a room and want teachers to have access to cameras and the radio, make sure this setting is enabled.
Tips for Using Teacher Traps
If you’re playing as a teacher, these are the main things to remember:
- Earn trap uses by allowing students’ Mischief progress to reach the required milestones.
- Activate cameras when you want to monitor suspicious classroom activities.
- Remember that cameras remain active for the rest of the class once enabled.
- Use the radio to identify students making noise from eating, Bubble Gum, phones, or computer games.
- Stay within 2 metres of the radio when activating it.
- Remember that only the teacher who activates the radio receives its tracking arrows.
- Save trap uses when you don’t immediately need a camera or radio.
- Check the Enable Traps setting before starting a class.
Teacher traps are useful for controlling the classroom without having to chase every student yourself. Cameras help catch students performing visible suspicious actions, while the radio gives you clues about students making noise. Using both at the right time can make it much harder for students to cause trouble unnoticed.
