Having some issues

Playing around with this exercise:


Your team has created a snowman as the centerpiece of an entry in teh Winter Snow Festival competition. To attract attraction to your display, you have set up colored spotlights that will turn the color of the snowman any one of four different colors. Create an initial world with four spotlights (spheres from the Shapes folder, of four different colors) and a snowman. Write only one method to change the color of the snowman. When the user clicks on a spotlight pass the color of the spotlight to the method and make the snowman change to be that color.




I can't figure out how to do that in one method for the life of me. Any hints?

Don't know if this will help or not, but I have published an online tutorial at http://www.dickbaldwin.com/alice/Alice0200.htm titled Understanding Lighting in Alice 2.0.

This is in the wrong forum. I am moving it and deleting your duplicate post, so all replies will be centralized.

See if this world attached is what you need. What I did was have one method with two variables and two parameters in the method;

[obj]whichSphere , [color]whichColor

were the parameters, and

[color]snowmanColor , [color]sphereColor

were the variables.

The method itself looked like this:

Do together(
 [color]snowmanColor set value to [color]whichColor
 [color]sphereColor set value to [color]whichColor)
Do together(
 [obj]whichSphere set color to [color]sphereColor, duration = 0 seconds
 snowman set color to [color]sphereColor, duration = 0 seconds)

As for events, I had a rather long (perhaps not-required) list:

When {mouse} is clicked on sphere, do world.my first method (whichSphere = sphere, whichColor = red)
When {mouse} is clicked on sphere, do world.my first method (whichSphere = sphere2, whichColor = none)
When {mouse} is clicked on sphere, do world.my first method (whichSphere = sphere3, whichColor = none)
When {mouse} is clicked on sphere, do world.my first method (whichSphere = sphere4, whichColor = none)
When {mouse} is clicked on sphere2, do world.my first method (whichSphere = sphere2, whichColor = green)
When {mouse} is clicked on sphere2, do world.my first method (whichSphere = sphere, whichColor = none)
When {mouse} is clicked on sphere2, do world.my first method (whichSphere = sphere3, whichColor = none)
When {mouse} is clicked on sphere2, do world.my first method (whichSphere = sphere4, whichColor = none)
When {mouse} is clicked on sphere3, do world.my first method (whichSphere = sphere3, whichColor = blue)
When {mouse} is clicked on sphere3, do world.my first method (whichSphere = sphere, whichColor = none)
When {mouse} is clicked on sphere3, do world.my first method (whichSphere = sphere2, whichColor = none)
When {mouse} is clicked on sphere3, do world.my first method (whichSphere = sphere4, whichColor = none)
When {mouse} is clicked on sphere4, do world.my first method (whichSphere = sphere4, whichColor = orange)
When {mouse} is clicked on sphere4, do world.my first method (whichSphere = sphere, whichColor = none)
When {mouse} is clicked on sphere4, do world.my first method (whichSphere = sphere2, whichColor = none)
When {mouse} is clicked on sphere4, do world.my first method (whichSphere = sphere3, whichColor = none)

Hope it helps to make yours, I wasn't going for efficiency when writing it.

Just so you know, you can change the color of the snowman within its properties, and you don't need to ues spotlights.

The spotlight method works too, but I prefer using the model properties.

You're a bit late in replying.

You should really consider the date of the last post before posting. Some forum people find it irritating.
