arrow_back Color Trail

Transcript

In this add-on, you'll add a colorful trail effect to the racers.

Here's how this effect works.

As the sprite moves forward, it creates clones of itself that change color, then disappear.

Clones are copies of the sprite that you program to have a specific behavior or action.

First, select a player sprite, open the control menu and add a create clone of myself block into the repeat loop that makes the racer move forward.

Then, add a racer to the clone block to the script's editor.

Any blocks you place after this block tell the clone what to do.

Click the looks menu, and add a change effect block.

To test this code, click the flag then press the correct arrow key to move forward.

Whoa, this is so awesome!

A bunch of clones appear, but they never disappear!

To make them disappear, add a delete this block from the control menu after the change effect block.

Click the stop sign to clear the stage.

Then test the code again.

No clones show up!

After the clones are created, they change color and delete so fast, you can't see them.

To fix this, add a repeat block around the change effect block.

Test it out.

Nice! Since changing colors ten times takes longer than changing colors once, you can see the trail effect.

Tinker with effect to make it your own.`` Change the value in the change effect block to alter the color effect change.

Add more change effect blocks to make the effect totally different.

This example shows what combining a change color effect and a change pixelate effect block makes.

This example combines change color effect and change ghost effect.

These are just some ideas.

Come up with something totally unique for your game.

Use the same method to add different trail effects to the other playsr sprite as well.

Now it's your turn.

Create a clone when the player sprite moves forward using a create clone of myself block.

Make the clone repeat changing colors then delete itself using change effect, delete this clone, and repeat blocks.

Tinker with the effect to make it your own by adding more change effect blocks and modifying the values.

Add the same effect, or a completely different one to the second player sprite.
