C＃Unity游戏测试

Question

I'm currently trying to get a game working in unity via C#. I think I did a good job to this point.

The game is a stacker Game:

A box will move from left to right and you press space to stack it If it's on the last box you placed its going further.

But now my problem is: the box is an object made in Blender.

But I want the boxes I'm creating underneath the current box the player is controlling to look like the box I made in Blender.

How can I achieve this? To this point I just use:

    GameObject cb = GameObject.CreatePrimitive(PrimitiveType.Cube);
    cb.transform.position = new Vector3(CurrentX, CurrentY, CurrentZ);

to create a normal cube.

I don't think that 2 lines of code can do everything you just mentioned. Hopefully, that's just a snippet from your code.

You have to export the box from Blender to .fbx , .blend or any other 3D model format that is supported in Unity. You can then import that file you exported into Unity. Here is a tutorial for that.

Make that imported cube/GameObject into a prefab then use the Instantiate function to create new cube each time instead of GameObject.CreatePrimitive .

Change your current code to

public GameObject boxPrfab;
GameObject cb = Instantiate(boxPrfab, Vector3.zero, Quaternion.identity) as GameObject;
cb.transform.position = new Vector3(CurrentX, CurrentY, CurrentZ);

Make sure to drag that prefab into the boxPrfab slot.

I assume the box GameObject that you want to spawn already exists in the scene. Then create a Prefab in the Project tab by right-clicking into the tab and selecting Create -> Prefab . Name the prefab something sensitive like eg BoxPrefab . Now drag'n'drop the box GameObject from the Hierarchy tab into the Project tab onto the newly created prefab entry.

Now you can add a public member variable to the script that is to instantiate the box spawns, eg like this:

public GameObject PrefabBox = null;

Then drag'n'drop the prefab entry that you created before from the Project tab onto that new property PrefabBox in the Inspector tab. In that same script you can instantiate spawns of the prefab eg by the following code:

GameObject boxSpawn = GameObject.Instantiate<GameObject>(
    PrefabBox,
    new Vector3(CurrentX, CurrentY, CurrentZ),
    PrefabBox.transform.rotation);

Find more info on instantiating GameObjects dynamically in the Unity3d docs.
