Thus it would make sense to have these variable easy to change both in edit mode and also experiment with them during runtime. Of course, we want our game to respond to user input. The most common ways to do that are using the following methods in the Update function of a component or anywhere else you like :.
Once we have user input we want GameObjects within our scene to respond. There are several types of responses we may consider:. GameObjects all have a transform property which enable various useful manipulations on the current game object to be performed. The methods above are fairly self explanatory, just note that we use lowercase gameObject to refer to the GameObject which owns this specific instance of the component.
This usually makes it easier to move objects in a manner that makes sense, as the local space axis will be oriented and centered on the parent object rather than the world origin and x,y,z directions. If you need to convert between local and world space which often is the case you can use the following:.
Since GameObjects are basically everything in your scene, you might want to be able to generate them on the fly. For example if your player has some sort of projectile launcher you might want to be able to create projectiles on the fly which have their own encapsulated logic for flight, dealing damage, etc….
First we need to introduce the notion of a Prefab. We can create these simply by dragging any GameObject in the scene hierarchy into the assets folder. This essentially stores a template of the object we just had in our scene with all the same configurations.
Once we have these prefab components we can assign them to inspector variables as we talked about earlier on any component in the scene, so that we can create new GameObjects as specified by the prefab at any time.
Often we need to communicate with other GameObjects as well as their associated components. Once you have a reference to a game object this is pretty simple. This is the straightforward bit, however actually obtaining the reference to the GameObject can be done in several ways…. This is the most straightforward. Then access the variable as above. We can tag GameObjects or prefabs via the inspector and then use the find game object functions to locate references to them. If we wish to access components in some parent object we can easily do this via the transform attribute.
Alternatively if we want to send a message to many other components or wish to message an object which is far up a nested hierarchy, we can use the send message functions, which accept the name of the function followed by the arguments.
As you can see, the code for this is a little bit more involved. The key thing to understand is that to cast a ray to where the mouse is pointing in 3d space requires the ScreenPointToRay transformation.
The reason for this is the camera is rendering a 3d space as a 2d viewport on your laptop screen, so naturally there is a projection involved to transfer back to 3d. Earlier we mentioned the Collider and Rigidbody components which can be added to an object. As you iterate with prototypes, tackle programming challenges, complete quizzes, and develop your own personal project, you will transform from an absolute beginner to a capable Unity developer. By the end of the course - if you are completing it through a school program - you will also be ready to put your skills to the test on the Unity Certified User Programmer Exam.
