Last time, I tried to directly draw to a texture attached game object. [ Previous: I tried to draw to Texture. Part1 ] In the blog log, looks like many people are reading the source, so this time I’m explaining more about the logic for beginners. Following is the C# source for drawing a texture, I added many comments so that you can understand easily this source. This ‘Paint_Line’ method... Read more
I created 3D model of Kid Merlion to use in my game app. [Link: Game App from Lab7] However, Kid Merlion is not so famous in the global wide. I believe that you know Merlion itself at least even if you don’t live in Singapore. In Singapore, actually, some Merlions exists. The most famous one is one staying at Merlion Park near Marina bay sands, and there are 2 Merlions there,... Read more
This time, I tried to directly draw to a texture attached a game object. This program is very simple. To test drawing to a texture, it’s drawing yellow color at the position where the game object is locating on the red texture which is attached on a field’s game object. [To realize this function] There are 2 game objects and 2 C# programs for this test. ‘Test_Draw’ is a program... Read more
If you happen the situation that the shape of your object was collapsed by Lattice Modifier like for example, following case. [Before applying Lattice Modifier] [After applying Lattice Modifier] Just applying, the shape of the target object was broken. (This is a face of Merlion 3D model I created…) [Reason] The reason is that when adjusting the Lattice flame to fit the target object in Edit mode, this phenomenon... Read more
When you copy an array in C#, for example, to copy from Array A to Array B, and if you want to use those amounts separately…, don’t write like following difinitely. Array_B = Array_A; I believe that it’s common sense for intermediate level, this is just passing Reference type. Therefore, if you change the amount of Array_B, automatically the amount of Array_A will be changed. (We can also say that... Read more
Last time, I tried Raycast by casting Ray from a game object. [Link: Physics: I tried “Physics.Raycast” from Game Object.] This time, I tried another way of Raycast. That is casting Ray from Camera. [Ref: https://docs.unity3d.com/Manual/CameraRays.html] [Test image to cast Ray from Camera] When clicking a game object which are scattered in 3D space by mouse, the shape and color (object name and tag) are shown. [Source code... Read more
You know, we normally use “Raycast” to identify Game Objects existed in certain direction from one location. The image is like that you emit virtual laser beam from a certain position, then if the beam hit somethings, you’ll get the information of the objects. 2 ways for Raycast The method of this, there are 2 ways like following Cast a Ray from a Game Object To identify the objects which...

To create UI, it’s normal to use uGUI which is standard functions of Unity now. UI objects which are put in a scene are rendered by Canvas object. So it’s necessary to use Canvas when you use any UI objects. This time, I tried and compared 3 Render Modes of Canvas component. (Ref: https://docs.unity3d.com/Manual/class-Canvas.html ) 3 Render Modes of Canvas Canvas have 3 Render Modes listed following. Screen Space –... Read more
Last time, I tried to move game objects by “Rigidbody“. (URL: http://blog-e.lab7sg.com/archives/84) This time, I tried basic ways to move game objects by “Transform“. [To specify the location to move in the flame] 1. position: Specify the position in a world space. 2. localPosition: Specify relative position from parent object (If it doesn’t have the parent, it’s same as ‘position’.) 3. Translate: Move to specified direction and distance. (Ref: https://docs.unity3d.com/ScriptReference/Transform.html）... Read more
To move game object in Unity, there are some ways. The one is to use ‘Rigidbody’. And also exist some ways for the ‘Rigidbody’. This time, I tried following 4 ways. [To specify the location to move in the flame] 1. position: completely teleportation 2. MovePosition: moving almost instantaneously (possible to interpolate in the intermediate position) [Add power or velocity to the object] 3. velocity: change the velocity in that... Read more
