5. Add More Receivers

Transcript

Now that you have one receiver working, you can copy it to add more receiver sprites to your passing drill.

In this video, you will create the rest of those receivers.

Right-click on the receiver sprite in the sprites area and select duplicate.

Do this as many times as you want receivers.

It looks a little weird that the receiver sprite catches the ball while the ball keeps moving to the edge of the stage.

Fix this by making the ball sprite stop at the receiver just like it does at the edge of the stage.

Click on the ball sprite.

From the operators menu, drag out an or block.

Remove the touching edge block from the repeat until block and place it inside the first blank of the or block.

Then from the sensing menu, place the touching color block into the other side of the or block.

To choose a color, click the color swatch on the block.

Then with the mouse pointer, click a color that all the receiver sprites have on them.

Place the or block back into the repeat until block.

The code reads, repeat moving until touching the edge or the color that's on the receiver sprites.

Test the code by clicking the flag.

The ball sprite should go back to it's starting location when it touches the edge or a receiver.

That's more realistic.

Tinker around with the numbers in your code.

If you think the receivers move too quickly, put a smaller number in the move block.

To change the speed at which the ball sprite turns, change the numbers in the turn blocks.

Explore, test, and make this passing drill your own.

Alright, here's the game plan.

Copy the receiver sprite by right-clicking it and choosing duplicate.

Change the ball sprite's repeat until to use or and touching color.

Tinker with the values.

Once you've done all that, move on to the next page to check out some add-ons.
