Throwing a ball

#1 I would like to know how to arc the ball pass... i.e. football being thrown and the arc/force is determined by how long the player holds the throw button. Or in the case of a basketball being shot towards the target basket with the same arc/force idea. Unfortunately my math sux, so I could use some tips/code samples on this as well. Thanks.

#2 There is some simple stock code which you can use to throw objects from the player. Check out inventory.cs and item.cs for the specifics. This code also has an example of how to create an arc.

Dealing with throwing a ball for a sports type game introduces some events you will have to code in.

Brief example:

- Throwing the object from the player
- Triggering a "throw" animation on the player
- Setting an arm thread to deal with the player's empty hands once ball is thrown
- The physics of the ball
- Enabling other players to interact with the ball (catch, kick etc)

And so on.

To get you started you could use the stock rigid body physics. This won't provide a good enough solution for a final product however it's the quickest way to get started and will provide you with a template to work from.

#3 Thanks for that tip Tim. I think I found what you're referring to in the SDK. Even the Shelled! game has script code that helps.

#4 I am still having trouble throwing an object. Helllllllllllllllp Meeeeeeeeeeeeeeeee!!!!! :0

#5 Download Shelled! (if you haven't already) it comes with the source code now. I have read through the code and found what I needed for throwing/shooting an object with an arc. Mr. Heldna gave some good hints there, on what activities need to happen to make it appear that the ball is being passed and caught.

#6 Okay, but now I am having trouble making an inventory. Can someone help me with this?

#7 Is there a way of throwing an object that is not in your inventory?

Yes. This means you'll have to create the item to be thrown.

Example:

datablock ItemData(ballThrown)
{
   className  = "Ball";

   // Basic Item properties
   shapeFile  = "~/data/shapes/ball/ball.dts";
   mass       = 1.5;
   elasticity = 0.2;
   friction   = 0.6;
   emap       = true;
};

function Ball::onThrowBall(%this, %obj)
{
   %item = new Item() 
   {
      dataBlock = ballThrown;
      rotation  = "0 0 1 " @ (getRandom() * 360);
   };

   MissionCleanup.add(%item);

   %obj.throw(%item);
}
