In GameMaker Studio, to have the camera follow a player character, you typically need to set up a view and link it to the player. You can accomplish this by adjusting the view properties either through the Room Editor or using GML (GameMaker Language) code.
Here's a simple step-by-step process on how to do this:
Create an Object for the Player You should already have an object for the player that has movement code applied to it.
Configure the Room Open the room where your game will take place and go to the views tab.
Link the Camera to the Player Now, in the same view settings:
Object following field to the player object.
Vbor properties which stand for horizontal and vertical border. This determines how close to the edge of the view the player needs to be before the camera starts following.
Code Example for Advanced Control
If you need more control over the camera than what the Room Editor offers, you can manipulate the view directly with GML. Here's an example that would typically be run in the
Step event of an object that controls the camera:
Remember to replace
oPlayer with the actual name of your player object. In the above script, we find the center position for the view based on the player's current location. This sets the camera to center on the player each frame.
It is important to note that as of GameMaker Studio 2, there are new functions for camera manipulation, such as
camera_set_view_pos, which allows for smooth camera movement and much more sophisticated control.
Make sure to check the official GameMaker documentation for the version you are using, as there may be differences in functions and best practices between versions.
