What is the first step in coding the VR Robot to move the VR Pen down to draw a black line? [Drive for] block set to 2000 millimeters (mm). Drag the [Turn for] block into the workspace and set the parameter to "400 millimeters (mm)". Drag the [move robot pen] block into the workspace and use the drop-down menu to set the position to "down". Drag the [move robot pen] block into the workspace and use the drop-down menu to set the position to "up".

Acolor class has three public, integer-returning accessor methods: getred, getgreen, and getblue, and three protected, void-returning mutator methods: setred, setgreen, setblue, each of which accepts an integer parameter and assigns it to the corresponding color component. the class, alphachannelcolor-- a subclass of color-- has an integer instance variable, alpha, containing the alpha channel value, representing the degree of transparency of the color. alphachannelcolor also has a method named dissolve (void-returning, and no parameters), that causes the color to fade a bit. it does this by incrementing (by 1) all three color components (using the above accessor and mutator methods) as well as the alpha component value. write the dissolve method.
