Prestitial & Interstitial Ad Specification Availability GameSpot Definition Prestitials and Interstitials are full-page Flash ads. The Prestitial appears to all users accessing the site from the front door and the Interstitial appears to users w/I the site once they have turned 4-6 pages. Users will be cookied, so they will only view the page once each day. A user could potentially see a Prestitial and Interstitial w/I the same session.

To Create a new clickTag command:

2. Select the rectangle tool. Switch the pen color to none, and the fill to any color. Make a rectangle that covers the ad area. In a interstital, this means the entire ad (it can overlap the boundaries)
3. Once this rectangle has been made, select the arrow tool, right-click on the rectangle and choose "Convert to Symbol". Select "Button" and click OK.
4. With the new button selected, open the properties window, and change color to "alpha" with 0%. The button should now be invisible (but still selected)
5. Open the actions window. Drag getURL (under the browsers/networks commands heading) into the actions box. In the URL field enter "_level0.clickTag" (without the quotes) and check the box next to expression. In the Window field select _blank from the pulldown menu. Entire code should look like this:


6. on (release) {
   • getURL(_level0.clickTag,"_blank");
   }

Note: Advertiser may use either target="_blank" or target="_top" for the Window Option
