Creating Grab/Throw Mechanic in 2D Platformer

I've been making a grab/throw system reminiscent of Mischief Makers. Here's what I've come up with:
When Player grabs Enemy:

• Enemy's collider is set to a trigger, preventing it from harming Player
• Enemy's position is set to the same position as Player's attack hitbox
• Enemy's move rate, velocity are set to 0, preventing it from moving around
• Enemy has a timer set for breaking out of Player's grab
  • if Enemy escapes Player's grab, Player is pushed backwards, and Enemy resumes Attack/Patrol states

When Player throws Enemy:

• Enemy's collider is set back to basic collider
• Enemy's move rate, velocity are set to normal state
• Enemy is sent flying via throwing force
• Player is pushed backward from direction of throwing direction

When Enemy is thrown:

• Enemy is damaged after colliding with other objects defined as "Ground"
• Enemy is reset to Patrolling/Attack states after a short delay

Main issues with grab/throw system at the moment:

• can't find a good way to switch enemy from Thrown state back to Patrolling/Attacking state
• unable to get a good throwing arch for enemies (enemies tend to slide across the ground when thrown)
• unable to stop enemy's previous velocity from pushing the player around when grabbed
  • This may be happening when I parent the enemy to the player's attack hitbox transform, but not sure

If anyone has tips on properly implementing a grab/throw mechanic similar to the one found in Mischief Makers, I would much appreciate it. Thank you for taking the time to read this.

 

You probably shouldn't use the IsTrigger, use a boolean in your script for that.
Doesn't it create an arc if you just add force to the enemy?

Code (CSharp):

1. Enemy.rigidbody.AddForce(direction, ForceMode.Impulse);

When do you want to switch the enemy's state from patrolling to attacking?

 

Here's the code I'm currently using for grabbing and throwing enemies:

Code (CSharp):

1. void GrabEnemy(Transform enemy){
2.  
3.         //make sure the enemy knows it's been grabbed
4.         enemy.GetComponent<Enemy>().IsGrabbed=true;
5.        
6.         //prevent enemy from falling out of player's hands
7.         enemy.position = transform.position;
8.         enemy.parent = transform;
9.         enemy.rigidbody2D.gravityScale = 0.0f;
10.     }
11.  
12.     void ThrowEnemy(Transform enemy){
13.         float h = Input.GetAxis ("Horizontal");
14.         float v = Input.GetAxis ("Vertical");
15.  
16.         //drop enemy
17.         enemy.parent = null;
18.  
19.         //stop grabbing the enemy...
20.         enemy.GetComponent<Enemy>().IsGrabbed = false;
21.        
22.         //...and throw the enemy
23.         enemy.GetComponent<Enemy>().IsThrown=true;
24.  
25.         //push them away from player
26.         //Vector2 throwVector = (transform.right * Mathf.Sign (transform.parent.transform.localScale.x)) * throwForce;
27.         Vector2 throwVector = new Vector2(h,v);
28.         enemy.rigidbody2D.AddForce (throwVector * throwForce);
29.         enemy.rigidbody2D.gravityScale = 1.0f;
30.  
31.         //push player back, as well
32.         transform.parent.rigidbody2D.AddForce (-throwVector * throwForce);
33.     }

As for the switching between Patrolling and Attacking: that's handled by the enemy itself when it sees the player.

 

You said

Can you be more specific on that question?

 

Please tell me you have found a way to implement it correctly. I am in desperate need of exactly this mechanic for my game!!
