A Healthy Solution to Pivot Problem - Unity 3D

I will today share a solution that i found more convenient and functional about Pivot ! So lets do it. 

 When we talk about 3D model ! Every character or an object have a pivot point.  That is very important that pivot should be in the center of that object. If it's not in the center we have to face many problem regarding this.

Keeping the model aside. If you have imported a model in unity you have to work with it independent of the graphics and designs. If your logic is dependent on models then you have to face many problems.  Lets come across with a common problem that we face in unity is pivot problem.
Models that we import sometimes have pivot disturbed position. And it's difficult to work with!

Now if we have to rotate an object  it will rotate around the pivot. The object will change not only its current axis but also position. Now that frustrating why the object changes it's position. It's satisfactory if there is nothing to do in the game scene ! because we can transform position manually in the scene. But if the object have to rotate it will rotate and will rotate around a large angle.

Now if you are an expert with 3D designer software you can change the pivot to 0,0,0. That also solve the pivot issue ! But what if we have to do the same without designer software ?When it comes to 3dmax or maya you can do it giving the object 0,0,0 axis in other words resetting the pivot points.

Lets see how we can do it in Unity 3D.



Now here is a tyre in the picture that have pivot away from it. Now if we give 180 degree rotation in the y axis of the rotation is will rotate around large axis changing it's position.Now that's hectic. When we have to rotate car's wheel. But the solution is easy.

First of all create an empty object. Then  Component --> add Physics --> Wheel collider in in the empty game object. And set the wheel collider according to the size of the wheel. Here the picture shows how its done.


Now take the wheel and make it the child object of the game object that have wheel collider in it.
This solution works fine. Try anything with it. It will surely pass your test.  I hope you don't have to wander around being frustrate about the problem.

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
