Create a simple Flash game

Tap the power of Flash’s ActionScript capabilities to build a simple game with animated characters.


11. Test your movie: you should see an evil bubble appear on screen every second, travel across the screen and disappear off the left-hand edge of the screen. As it takes more than one second for the travel to happen, it’s possible to have many bubbles on screen at once. The code we’ve just added controls how often (in frames) a new bubble is created. If you want more, lower the “>30” bit of the code to, say, “>20”. If you want fewer, increase that number.


12. We’re going to add some collision detection to the bubbles. When they hit Madame Octopus, we want to end the game (the aim being to avoid the bubbles for as long as possible). To do this, we need to first give MO an instance name so we can refer to her from the bubble class. Click on the Madam Octopus then enter an instance name of ‘octopus’ in the Properties panel.


13. Create a new symbol (Insert > New Symbol), drag it onto the stage and give it an instance name of endGamePanel. Inside the endGamePanel, create a ‘Game Over’ screen to suit (or check out our version). Set the alpha property of your symbol to 0. Create a new layer in your main timeline. Name it actions, then add the following code, or copy and paste it from the cover CD file Step 13a: Var tmpscore = 0; var playing = true; function endGame() { playing = false; _root.endGamePanel._alpha = 100; } Edit and enter the code below inside the onEnterFrame function, or copy and paste it from file Step 13b on the cover CD. This uses the built-in hitTest function to check if a bubble is touching MO. If it is, the bubble is removed and the endGame() function is called: if(this.hitTest(_root.octopus)) { this.removeMovieClip(); _root.endGame(); }

HP OfficeJet 250 Mobile Printer

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.
