#JustCode Challenge Week 13 – Xojo Speed

#JustCode Challenge Week 13 – Xojo Speed

Published September 14, 2018 by Paul Lefebvre

When Geoff and I were driving around Germany with Christian Schmitz of MBS Software before the MBS Xojo Conference started, the topic of speed limits on the autobahn came up. Christian mentioned than many cars in Germany have the speedometer set to display a speed that is a little higher than what you are actually doing. I have noticed that my Toyota Tacoma shows 70mph on the speedometer when it is really going more like 67.

Geoff wondered if there was a way to determine how accurate your car’s speedometer was and it made me think of a Xojo iOS app I had made a while ago: Xojo Speed.

Run Xojo Speed on your iPhone while you’re driving and it uses the iOSLocation class to calculate the miles per hour or kilometers per hour in a large, easy-to-read display.

#JustCode Challenge Week 12 – MultiTemp

It’s week 12 of #JustCode and I’m in in Munich, Germany at the MBS Xojo Developer Conference! I’ve never been to Germany and had no idea what the temperature would be, so instead of using the Weather Channel, I found a web API called OpenWeatherMap and built an iOS app to fetch the weather for display in a table. I even implemented the new table refresh feature added to Xojo 2018r2.

#JustCode Challenge Week 10 – NetTank

#JustCode Challenge Week 10 – NetTank

Published August 24, 2018 by Paul Lefebvre

For the 10th week of the #JustCode Challenge I took a look at networking. For my project this week I’ve created a networked version of the Combat game, which has two tanks on the screen shooting at each other. The network version allows you to control one tank with the app running on your computer and someone else to control the other tank with the app running on their computer. I call it NetTank.

#JustCode Challenge Week 9 – Quote Web Service

#JustCode Challenge Week 9 – Quote Web Service

Published August 17, 2018 by Paul Lefebvre

We’re wrapping up week 9 of #JustCode with a web app that demonstrates a web service, JSON and SQLite. The web app functions as both an app with a UI and a web service. It lets you enter your own quotes which are saved in a SQLite database. The web service randomly fetches a quote and returns it as JSON.

#JustCode Challenge Week 8 – JumpStart App Launcher

#JustCode Challenge Week 8 – JumpStart App Launcher

Published August 10, 2018 by Paul Lefebvre

A long, long time ago (1989) one of the first apps I ever made was an app launcher for the Atari ST. I called it JumpSTART. I originally wrote it in GFA BASIC and then later re-implemented it in Pascal (OSS Personal Pascal, technically).

When I got my first modem I went online with Genie and Delphi and uploaded JumpSTART as freeware. Even though it was freeware, I got a few checks in the mail from people that liked it.

I was reminded of JumpSTART when I saw my dock getting crowed. I thought replicating JumpSTART in Xojo would be a good project for week 8 of #JustCode. Though let’s just call it JumpStart this time around.

#JustCode Challenge Week 7 – Pitch Tracker

#JustCode Challenge Week 7 – Pitch Tracker

Published August 3, 2018 by Paul Lefebvre

As many know, I’m a big baseball fan. I was recently at Sea Dogs game (our local AA minor league team) and was sitting behind home plate alongside many scouts who were carefully watching the pitchers. I noticed several were tracking pitch counts using an app on a tablet or laptop. I thought that would make for an interesting app to make in Xojo, so this week I’ve made an iOS app (I’m on an iOS roll it seems) to track the location of pitches, similar to what I observed the scouts using.

The app shows a grid of the strike zone and you tap where the pitch was. You can use the buttons on the bottom to mark the pitch as a ball, strike or in play changing its color. Click the Reset button to clear the pitches for the next batter.

#JustCode Challenge Week 6 – Bubble Popper

Published July 27, 2018 by Paul Lefebvre

For this week’s app, I created a simple iOS app where you tap on “bubbles” to pop them. This was actually suggested to me by Dana Brown some time ago as something that would make a great diversion for her son. I have found it helpful with some of my younger nieces and nephews.

This iOS app demonstrates the use of a Canvas and the detection of taps. When all the bubbles have been popped, more are added. It never ends!
