Unity

When we using Unity to make a 2D game, if you want to keep the aspect ratio of the camera shooting unchanged, but you want to dynamically adjust the shooting range, then we can adjust the orthographicSize parameter.

In the past, I always used Resources.LoadAll<Sprite>() to create an Array<Sprite> object, but today, when trying to optimize the program, I tried to change to Resources.Load<Sprite>() to read a specific Sprite.

Recently I migrated my developed Unity game from Windows to Mac OS, but when I connect to my test device and compile the APK file to run, I got the following error message:

If you are making a game for mobile device in Unity, we usually don't set the screen to display horizontal and portrait two version for playing. After all, it is too difficult for art design and scene design..., At least it is absolutely impossible when I develop independently.

To make the SortingIndex() function effective, we need to set the Sorting Layer.

Today I want to record how to use SetSiblingIndex() function to set the order of child game object under the parent game object in Unity.

The random numbers can be seen everywhere in a game, regardless of the character's ability or the enemy location, we can all use random numbers to determine.

In the process of making games with Unity, we usually need to deal with some collisions of game objects. For example: Get items, Hit the wall... and so on in different situations. At this time, we can OnCollisionEnter() and OnTriggerEnter() to handle collisions and trigger events.

I recently use Unity to develop when a snake game, I want to delete the head game object when my snake head collides with another snake's body, I need to use OnTriggerEnter2D() to set the collision determination.

In the process of making the game with Unity, we cannot manually place all game objects we need. In other words, sometimes we need to automatically generate or delete game objects.
