Unity Study the tutorial

I'm referring to B The one standing here UP Video learning , Very good ！ Xiaobai is friendly ！

【unity2022 introduction 】 Integrate Unity Official tutorials design the best learning route ,Unity Introduction series of intensive lectures , Ongoing update ...._ Bili, Bili _bilibili

1 Add and load project resources

Add project resources

This case uses Unity In the official resource store FPS Project resources of the game ：Creator Kit：FPS.

Official resource address ：Creator Kit: FPS | course | Unity Asset Store

Select Add to my resource

Load into Unity

stay Unity Hub Create a new one in 3D project , After opening, follow the following path

Top menu Window -> Package Manager -> My assets -> Download after Import It's done.

 

2 load Scene

Here we don't directly create a blank scene as before , Use the resources given by the imported project to create , Top menu bar FPSKIT ->  Create new Scene, Choose a suitable place to store （ It's recommended to put it in Scene Under the table of contents ） You have created the scene you need now .

You can find , This scenario has been packaged with a series of things that need to be used , It provides very convenient resources . 

By the way , The original intention of this small game is to further understand the process of game production , The code part has not been covered , Need to take Follow the tutorial , natural To learn .

3 Add shots from the preform Targets

The object here provides “ One's own ”—— Red blood cells and “ The enemy ”—— Bacterial monster , Respectively from the Prefabs Of Targets Drag in two categories Targets, The quantity and location are customized .

4 Manage game objects

4.1 Create grouping relationship

The same level （ scene ） There will be a lot of shooting aimed at the target , So many goals need to be grouped . stay hierarchy There is no folder in the view to manage so many game objects , We can create an empty game object as the parent object , Put the same scene Targets As children of the same parent , Pictured

4.2 Distinguish relative coordinates & World coordinates

• As the grouping relationship of the above parent-child relationship , Find sub objects Transform Components  -> Position The coordinates have become different from before , This is because the coordinate system of these sub objects has been converted from the world space coordinates of the previous scene to the relative space coordinates
• meanwhile ,Targets Of this parent object Position, Will be One composed of all sub objects box The center of the whole
• So what if we want to synchronize the position of these sub objects with the previous world coordinates ？ hold Target The coordinates of are changed to (0,0,0), Then adjust the position of the sub object , That's it .

5 Make a prefabricated part by yourself

Assets -> Creator Kit-FPS -> Art -> Models -> Characters, Find the preform GermSpike, Open this prefabrication and find that it is composed of three game objects

Let's not delve into what it originally contained .

Add it to the scene, try to run and find that it can't hit , Judge the lack of rigid body and collision body components , Therefore, it needs to be further improved .

5.1 Add rigid bodies and collision bodies

To achieve collision , You need to add rigid body and collision body components , rigid body -> Rigidbody, Colliding body -> Sphere Collider, At the same time, give the collider a fitting shape

5.1 add to Target Script

You need to hang another Targets There are scripts , Used to give life value 、 fraction 、 Sound components, etc .

5.3 Save as a new preform

Drag the object with the above components into the other two targets In the directory , It is preserved as a new prefabricated body , You can directly drag it into the scene when you need it .

6 Create a new scene

Here we use LevelLayout Script components , I don't delve into how it was written here , Just use it first .

open LevelLayout -> Click on Editing Layout,Add perhaps Remove To add a new scene .

7 Create doors and keys

To enrich the game , In the project, you can also add a door and a key to open the door to each level , These resources are available in Prefabs You can find it in the library , Add doors and keys and name 、 Just connect .

8 Modify the weapon

This weapon part is actually to select and add , So I won't go into details , Just watch the tutorial .

9 Add game end condition

I think the main thing to learn in this link is —— Application of collision body . Knowing that collision bodies can also be achieved Trigger the contact effect to execute the game end script Purpose , The key is to put Is Trigger The checkbox for is turned on .

Give him a box Collide with the body and hang a script at the end of the game .

thus , The game making process in the tutorial is all over .

10 Release the game

Click on File -> Build Settings, Select the platform you want to publish and Build Just go .

After saving ：

summary

It took a day to learn how to make one 3D The process of the little game , To study the ： Use of coordinate axes 、 Familiar with the right button +WASDQE Key to realize the first view movement 、 Set the game object 、 Hang script 、 Give the door and key 、 And setting the end conditions .

I learned a little , I will continue to learn about deeper programming later .
