Controlling a falling character in 2d space

For my prototype, I want to create a character that falls in 2d space and can only be controlled by "sliding" along the x and y axis. Is there a playmaker way or a script that will help me make this happen? Please let me know

 

PlayMaker method: http://www.hutonggames.com/sampleScenes/AddForce/AddForce.html
Unity method: http://docs.unity3d.com/Documentation/ScriptReference/Rigidbody.AddForce.html

 

thanks a lot for the reference, I'll have more ideas

 

its a 2d game. how can i control the character by sliding him from side to side

 

think of it as a top down shooter with gravity except the player is falling downward. its a 2d game basically. how can i constrain the character to x and y axis to help him avoid collisions

 

The fact that you setup a 2D project in Unity and activate the 2D perspective means that you are automatically constrained to the X and Y axis. When you AddForce to a rigidBody2D, you only have the option to add the force on the X and/or Y axis. Once again you are automatically constrained to the X and Y axis.

With that said, there are a couple ways to trigger the call to AddForce...
1) Using onscreen touch events
2) Or using accelerometer events

 

I have my character falling, how do get him to move left and right? I saw the AddForce and was wondering how to implement this. It say's I can't add a character controller since the rigid body is added and collider is on

 

Do you want to use the accelerometer?

Or do you want to use on screen controls?

Or do you want to have the user touch anywhere on the left side of the screen to go left, and anywhere on the right side of the screen to go right?

 

For the prototype, i wanted to map slide left with the F key and slide right J key. I will implement the touchscreen controls later. For the Keyboard keys, I want to recreate the sense of the player in front of an arcade machine

 

void FixedUpdate() {
if (Input.GetKeyDown(KeyCode.F)){
rigidbody2D.AddForce(new Vector2(-100f*Time.deltaTime,0f));
}else if (Input.GetKeyDown(KeyCode.J)){
rigidbody2D.AddForce(new Vector2(100f*Time.deltaTime,0f));
}
}

 

I created a new script, what are the following steps?

 

Attach the script to the GameObject that contains the RigidBody2D of your character.

 

where do i paste the code in Mono Develop, after void start? and after that how is it implemented?

 

Sure you can put it after void Start.
Once you attach it to the GameObject, it automatically works.

 

Do I create this script with Javascript or C#? I'm still having difficulty

 

C#

 

No luck. its not working or updating in Unity after its pasted

 

Ok I updated the code in my earlier post. Try it now

 

I'll give it a shot. Would you mind helping me out more? I have an ambition of putting it on kickstarter for some additional funding …This is my first attempt at making a game and I really believe in this concept and I have other mechanics too. I plan on making a demo first and using it to get feedback to start building the final game
