Coin 8: Changing the position of the coin on the stage after click.

• This is a continuation of the Coin Project 1-7

1. Open your coin movie. Double click on the coin movie clip on the main stage. The current timeline of the coin1 movie clip has 6 frames, The first frame has the button in it and a stop. The additional frames are for the breaking up of the coin after it was clicked.

To make the movie more interesting, we can reposition the coin after it breaks up and returns to the frame 1. The _x position is regulated by the variable mania, and the _y variable is regulated by the variable ruby.

Click in frame 6 of the actions layer of the movie clip. Hit your F7 key to insert a blank keyframe. Highlight the frame and open your action panel.

2. First we need to reset mania using set variable. Click Actions=> variables=> set variable. In the variable field type in the path to the variable <dot> mania, or _root.mania. Click in the value field. We need to generate a random whoile number for x between 0 and 550, or the width of the stage. To do this we will Use round to generate a whole number. Click Objects=> core=> math=> methods=> round. Click in the bracket for the parameters for Math.round. Add the script for random by going objects=> core=> math=> method=> random. After this is placed in the brackets we need to add the multiplier to set the random number between 0 and 550, by adding * 500. Check expression so it is calculated. The result will look like this:

_root.mania = Math.round(Math.random()*550);

3. To reset ruby we use set variable again. Click back on your bottom script in the script panel so the new script goes under the last. Click Actions=> variables=> set variables. In the variable field type in the path to the variable <dot> ruby, or _root.ruby. Click in the value field. Click Objects=> core=> math=> methods=> round. Click in the bracket for the parameters for Math.round. Add the script for random by going objects=> core=> math=> method=> random. After this is placed in the brackets we need to add the multiplier to set the random number between 0 and 400, by adding * 400. Check expression so it is calculated. The result will look like this:

_root.ruby = Math.round(Math.random()*400);

The coin will now change position after it breaks up.

The next tutorial sets up starting and ending screens and a time limit.
