In this add on you'll program your sprites to change colors similar to how athletes wear different jerseys.

First, decide which athlete gets to change into more colorful apparel.

In this example, athlete two will be the one to showcase a new uniform.

Click on athlete two.

The change effect by block from the looks menu has different effects that will make the athlete's outfit change.

Drag out this block.

Right now it says change color effect by 25.

Click the block to try it out.

Try different values in the block like 10, or maybe negative 20.

If you keep clicking it, your sprite changes colors to look like it's wearing different outfits.

Sprites can change other effects besides color.

Click on the triangle drop down to see different effects and select brightness.

Click the block to try it out.

Great! The sprites uniform gets brighter and brighter.

In baseball and basketball the home team will typically choose to wear a lighter colored version of it's uniform.

In this example, athlete two wears a variation of it's jersey so it has a slightly different uniform for home and away games.

Place the change effect by block inside the repeat loop, choose the effect you want and test your code by clicking on the stack.

Drag out a clear graphic effects block to reset your athlete's uniform to it's original color.

Snap it to the bottom of the repeat loop.

Click the block stack to check it out.

Notice how the sprite changed colors before returning to normal.

All right, here's the game plan.

Add a change effect by and clear graphic effects block to the repeat loop.

For an added challenge, use different effects so that your athlete looks it's absolute best when it's performing.
