Step-by-step Guide
Creating a security camera in Gamemaker Studio is a complex process, but with the following step-by-step guide, you’ll be able to code your own in no time:
Step 1: Setting up
First, create a new project in Gamemaker Studio and import any necessary assets for your security camera, such as sprites and sound effects.
Next, create a new object in the Object Editor and name it “obj_camera”. This object will represent your security camera in the game.
Step 2: Creating the camera view
Within the obj_camera object, add a Create Event and use the following code to set up the camera view:
camera = view_camera[0];
view_xview[0] = x - view_width / 2;
view_yview[0] = y - view_height / 2;This code sets the camera to be the first view_camera and centers it on the obj_camera object.
Additionally, you can customize the view_width and view_height variables to determine the size of the camera’s view.
Step 3: Implementing motion detection
Next, add a Step Event to the obj_camera object and use the following code to detect motion:
if (!camera_motion_detected)
{
if (abs(x - previous_x) > motion_threshold || abs(y - previous_y) > motion_threshold)
{
camera_motion_detected = true;
audio_play_sound(snd_motion_detected, 1, false);
}
}
previous_x = x;
previous_y = y;This code compares the obj_camera’s current position to its previous position and checks if the distance exceeds the motion_threshold. If motion is detected, a sound effect (snd_motion_detected) is played.
Step 4: Displaying the camera feed
Create a new object to represent the camera feed. This object will display the view from the obj_camera object.
In this new object, add a Draw Event and use the following code to display the camera feed:
draw_set_blend_mode_ext(bm_subtract, bm_subtract);
draw_surface(surf_target, x, y);
draw_set_blend_mode(bm_normal);This code uses the surf_target surface to draw the camera feed and applies a subtract blend mode for an authentic security camera effect.
Note: The surf_target surface should be created and updated in the Step Event of the obj_camera object.
Step 5: Adding additional functionality
If desired, you can add additional functionality to the security camera, such as a security alert system, controls to rotate the camera view, or image capture functionality.
Use the Step Event of the obj_camera object to implement the additional functionality you desire.
And there you have it – a step-by-step guide to coding a security camera in Gamemaker Studio! Make sure to test your game regularly and tweak the code as needed to achieve the desired results. Good luck with your game development!
Setting up the game
Before we start coding the security camera in Gamemaker Studio, we need to set up the game environment. Follow these steps:
Step 1: Create a new project
Open Gamemaker Studio and create a new project. Set the game resolution and other project settings according to your preferences.
Step 2: Create the game objects
Create the necessary game objects that will be used by the security camera system. For example, you can create an object for the player character, the security camera, and any other objects that are relevant to your game.
Step 3: Set up the room
Create a new room and add the objects you created in the previous step. Set the room dimensions and other properties according to your game’s needs.
Step 4: Place the security camera
In the room editor, place the security camera object at the desired position. Adjust its properties, such as the field of view and rotation speed, to achieve the desired effect.
Step 5: Add movement controls
If your game requires the player to move around, add the necessary movement controls to the player object. This will allow the player to navigate the game world and interact with the security camera system.
Once you have completed these steps, you will have the basic game environment set up and you can proceed to code the security camera system in Gamemaker Studio.
Creating the security camera object
In this section, we will create the security camera object that will be responsible for detecting and tracking the player’s movements. The camera object will be placed in the room and will have a field of view that it will scan for any movement.
To create the security camera object, follow the steps below:
Step 1:
In GameMaker Studio, click on the “Create” button in the toolbar to create a new object.
Step 2:
In the “Object Properties” window, set the name of the object to “obj_security_camera”.
Step 3:
In the “Events” tab of the “Object Properties” window, click on the “Add Event” button and select “Create” from the list to add a “Create” event.
Step 4:
In the “Create” event, write the following code:
image_speed = 0;
image_index = 0;This code sets the image_speed and image_index variables to 0, which means that the camera object will not display any animation and will use the first image in the sprite instead.
Step 5:
Add a new event by clicking on the “Add Event” button and select “Step” from the list to add a “Step” event.
Step 6:
In the “Step” event, write the following code:
// Check if the player is within the camera's field of view
if (collision_rectangle(x - 128, y - 128, x + 128, y + 128, obj_player, false, true))
{
// Do something if the player is within view
// For example, sound an alarm or send a notification
show_message("Player detected!");
}This code checks if the player object collides with the rectangle area defined by the camera’s position and a width and height of 256. If the player is within this area, a message will be shown indicating that the player has been detected. You can customize this code to perform any actions you want when the player is detected.
With these steps, you have created the security camera object in GameMaker Studio. You can now place this object in your room and adjust its properties as needed.
Implementing the camera movement
Once we have set up the security camera sprite and its initial position, we can now implement the camera movement in Gamemaker Studio. First, we need to create variables to store the current position of the camera, as well as its target position.
Next, we can use the lerp function in Gamemaker Studio to smoothly move the camera towards its target position. This function takes in three parameters: the starting position, the target position, and a value between 0 and 1 that determines how close the camera gets to the target position. We can use a step value of 0.1 to start with.
To make the camera follow the player, we need to update the target position of the camera based on the player’s current position. We can do this by adding the player’s x and y coordinates to the camera’s starting position. We can also use the clamp function to keep the camera within the bounds of the room.
Here is an example code snippet that demonstrates how to implement the camera movement:
// Initialize variables var cam_x = x; var cam_y = y; var cam_target_x = 0; var cam_target_y = 0; // Update camera target position based on player's position cam_target_x = player.x - cam_xstart; cam_target_y = player.y - cam_ystart; // Smoothly move the camera towards its target position cam_x = lerp(cam_x, cam_target_x, 0.1); cam_y = lerp(cam_y, cam_target_y, 0.1); // Keep the camera within the bounds of the room cam_x = clamp(cam_x, room_width / 2, room_width - view_wview[0]); cam_y = clamp(cam_y, room_height / 2, room_height - view_hview[0]); // Set the camera position view_xview[0] = cam_x - view_wview[0] / 2; view_yview[0] = cam_y - view_hview[0] / 2;
With this code, the camera will smoothly follow the player within the bounds of the room. You can adjust the step value in the lerp function to change the speed of the camera movement.
Remember to update the camera’s position every step in your game’s main loop for smooth camera movement. You can also add additional features to the camera, such as zooming or rotation, to enhance the security camera effect in your game.
Adding security features
When coding a security camera in Gamemaker Studio, it is important to include certain security features to enhance the effectiveness of the camera system. These features can help in preventing unauthorized access and ensuring the smooth functioning of the camera.
Here are some key security features to consider:
- Authentication: Implement a secure authentication system to restrict access to the camera feed. This can be accomplished by requiring users to enter a username and password or by using biometric authentication methods.
- Access control: Set up permissions and access levels to control who can view the camera feed. This can be done by assigning different user roles with varying levels of access rights.
- Encryption: Encrypt the camera feed to prevent unauthorized interception or tampering. This can be achieved by using SSL/TLS protocols or other encryption methods.
- Alerts and notifications: Set up a system to send alerts and notifications in case of unusual or suspicious activities. This can involve sending email alerts, push notifications, or triggering alarms.
- Monitoring and logging: Implement a logging system to keep a record of camera activities and user access. This can help in monitoring and auditing any security breaches or unauthorized access attempts.
- Physical security measures: Install the camera in a secure location and protect it from physical tampering. This can involve using tamper-proof hardware, mounting the camera in a vandal-resistant housing, or employing physical security measures at the camera site.
By incorporating these security features, you can ensure the integrity and effectiveness of your security camera system in Gamemaker Studio.
