Take a look at your favorite game. Odds are good that there is a scrolling background of some type. Think Super Mario Brothers.
Mario is a bit different than what we’re after though. The background in Mario is a single graphic that scrolls as Mario moves through the world. What we want is a scrolling background that loops forever. We’re going to scroll horizontally like a platform jumping game, but the same concept works vertically. Read more »
Some games, I’m thinking tower defense, need to give the player the ability to drag symbols around. But you don’t always want to give the player free reign to drag it anywhere. Maybe you want them to only be able to position symbols in a grid. That’s what we’ll create here using ActionScript 3.
This is what we’re going to be creating. Try dragging the green square. It will snap so that it’s always in one of the grid squares.
Earlier this week I Googled for how to find the dimensions of an image using Java, and most of the solutions were way more complicated than they needed to be. Most of what I came across was code that opened the image and parsed through the binary code to get the dimensions.
Yes, there’s an easier way.
The BufferedImage class has a couple built in methods that will get the dimensions without much trouble at all thanks to the getHeight and getWidth methods.
Want to create a random color in Java? With a bit of math, plus Math.random(), it’s pretty easy.
A bit about colors
Colors on the computer are made up of a red, green, blue triplet; typically called RGB. And each of the 3 pieces can be in the range from 0 to 255. Java also allows us to create a color using floats for the values in the range of 0.0 to 1.0, or from 0% to 100% of that color. We’re going to use the floats.
As an example, pure red will have an R value of 1.0, a G value of 0.0, and a B value of 0.0.
So we know what numbers we need, but we want ’em random. Read more »
I’ve only recently put images into my signature in Outlook and noticed that most of the time the images weren’t included in replies. Turns out when someone sends a message in plain text Outlook defaults to replying in plain text.
It’s easy enough to change the format to HTML, but the plain text version of the signature was sticking.
The tip I came across today was that, once you switch the format to HTML, you can just right click on the plain text version of the signature and pick the right one.
Up until about a week ago my normal process for testing PHP code that sends email was to run sendmail through WAMP and send to my email address. I’m thinking about the amount of time I could have saved had I found this plugin when I first started.
The Test Mail Server Tool runs on your computer and listens on port 25 for outgoing emails, just like sendmail would. Difference is that instead of sending the email out it just saves it to a folder on your computer.
So with your PHP sending out mail messages on port 25 Test Mail Server picks it up, dumps the entire message into a mail file, and optionally opens it up for you. On my notebook they’ll open up in Thunderbird and look almost like a standard email. Only flaw I’ve come across is that images don’t show, and Thunderbird doesn’t give the normal option of viewing images. Could be that the images are coming off of localhost though. Haven’t tried it pulling images from anywhere else.
It’s moved homes as well. My plugins are going to move back to Reliti.com.
And I don’t plan on taking the old version off the WordPress plugin site, but I also don’t plan to update that version either. Updates will be done to the version at Reliti.
