Look at , lerp , Destroy gameObject - Unity

Look at
 Lets just discuss about the code and look at use. I have used the look at function to change the direction of the camera while the game is playing. As i have created a character. Which falls on the ground. Now In order to show the ball falling look at function is used that shows while playing.


Now here the script is added where in the target section i have added a moving cube. That the camera demands the object on which it have to focus. Now lets see the code that simple to understand. 


Now here the Transform object reference is given which demands a particular object. That is given be given in the picture above shown. 

Lerp 
Vector 3.lerp is used to change the position of an object between two points.
In this section i have added the lerp attribute to the camera. So the camera will move between two points. Lets see the code things will get more clear.

Here on the first line a Vector3 is declared. Where in the awake transform position will assign the current position of the object. Then in update the position change method will be called. Where  two positions are defined. And below that it take the command. On which pressing the particular key. It will change the camera position.   
Camera Positon 1:

Camera Position 2:

Now the pressing of Q and E changes the camera position.

Destroy GameObject 
As in unity every character is considered as object. Now if you want to destroy the the object this code is needed.
Now the object that will be added in the others will be destroyed. If you want to destroy the object after some time. Then you have seen the code in the comment Destroy(other,3f) 3f means that it will destroy the object after 3 seconds. Hence the space occupied will be empty.

How to move an object in Unity 3D

How to move an Object Backward and Forward in Unity 3D !  First of all lets discuss some of the key words that are necessary to understand.  Vector 3: Its a representation of 3 vector points. You have listened the x ,y and z axis. So here vector 3 takes all the 3 values. The points in the back and forward will be (0,0,-1), (0,0,1) respectively. Time.deltatime:  Function is used to make the game rate independent. If you multiply the variable with time.delta time it means you are saying that i want to move the object 10 meter per second. Basically you use delta time to update your movements. Transform.translate:   Transform.translate is basically used for the movement of the object as it takes the 3 axis value to move the object.  It's related to the distance the object will move. Now lets see some practical example to make a object working. We take a cube for the example purpose. Then add script to it. Now lets see the played situation. As my object is mo

Input.Getaxis, OnMouseDown, GetComponent< > - Unity Scripts

In This Blog We Will Discuss Some more Keywords. Input.GetAxis : In this picture a chunk of code is placed. You will see that Input.GetAxis("Vertical") returns a value. The value is from 1 to -1. When there is no key pressed the value is zero. Actually it returns the value of virtual axis. If we use Debug.log then the console will show some value on clicking the right or left button that will be constantly changing.  Other thing is that Vertical is pointing towards the built in inputs. As you can see in the picture above that the vertical have some columns in it. Where the vertical have positive and negative button which give positive or negative float value on event pressed. Whereas if we don't want to use these inputs . We can write code instead of writing Vertical or horizontal in the brackets of input.getaxis. We can write it as Input.GetAxis(keycode.space); .  Here the space key is assigined and it will return some value. OnMouseDown() : OnMouse

Vector Math - Unity

Vector Math  Addition:  As you that the vector addition is defined by the combined effect of two or more than two vectors. When the tail of one vector is added to the head of other vector addition is made. This can be defined by a parallelogram.Actually joining two vectors result into a new vector. Subtraction:  Vector subtraction is performed to get the direction and distance from one object to another. The addition and subtraction of vectors is similar as the subtraction of vector will have negative negative magnitude that means opposite in direction. As in subtraction head to tail rule is also used. Dot Product : The multiplication of two vectors will result in a scalar quantity. Where Theta is the angle is multiplication of the two vectors is 0 than its perpendicular. In unity we use Mathf.Cos. Which perform equal-ant function. Cross Product: The result is perpendicular to the two vectors. The "Left hand rule" can be used to remember the d
