The rotating input connector can have an oscillation limit angle that makes the rotating input reverse when the angle is reached. There is also an angle that is just the oscillation offset or start point. It’s hard to describe that start angle although I should just call it…
Continue readingI got a complaint, albeit a very friendly and not “complainy” one, that the Linkage software isn’t handling the pen (stylus) on a Windows tablet properly. I implemented pen-to-mouse conversion code that seems to be working. My HP Spectre x360 came with a stylus so I was able…
Continue readingAsynchronous operations are commonplace in modern software. In C# (C-Sharp), opening a file can be asynchronous with the code asking the operating system to open the file and the operating system responding with “ok, I’ll do that. You can go do something while you wait.” This type of…
Continue readingI create videos using an MPEG encoder for Windows. It’s very hard to find a video encoder that can be used by software like the Linkage program – too many video programs just embed their encoder or require you to buy that software to use their encoder. Since…
Continue readingI’m about ready to turn the Beta Linkage program into the official production version. The only problem is that I still want to do more work on it. It feels incomplete if it can’t move a cam to make it meet a follower. In other words, the follower…
Continue readingThanks to a user, I fixed a few bugs in the spline/cam simulation code. Splines that are not fastened to a link or connector are now treated as part of the “ground” and can be used as cam-like shapes without producing simulation errors. Speaking of connectors; a cam…
Continue readingThis post turned out to be wrong. The email subscribers stuff is not working at all. There is a problem with my WordPress installation and publishing always fails the first time I do it for a new post. A second try at publishing works fine. It may be…
Continue readingI had a running error, or something like that, in the Linkage program. I had targeted 30 frames per second for animations and I used a 33 millisecond target time for each frame. If a frame took less than 33 milliseconds to compute and draw, I would add…
Continue readingI have a specification at work that says my software needs to see a URL like this: https://blog.rectorsquid.com/derf?test={id}&test2={data} and then open the URL as if it were something like this: https://blog.rectorsquid.com/derf?test=12345&test2=hellothere I first wrote some code that would split the input using the open curly brace as a…
Continue readingI had to write code to show a variable-sized set of images in a view. Each mage fades in then shows for another 5 seconds before the next image fades in. I found some code at Stack Overflow that was partially complete and hinted at a way to…
