    Thank you, there are still lots of cars to do. I would like to hear your suggestions for new cars, and I will add them to my to-do list. Thanks.

    The Peugeot RCZ would be cool :cool:

    Edit: Something else I've been wishing to suggest is a calibration feature, because I often have to keep the iPad slightly inclined to keep the car running straight.

    Thanks for the suggestion, added to my list.

    As for the calibration. Do you see the same issue in other games? Does the issue repeats after a clean restart? I will look into that. Thanks.

    I don't have any calibration issues.

    Awesome. Am I right in thinking you want to keep the car selection free of higher end supercars like lambo's and the like? (which is awesome -- your selection is much more interesting without them)

    I'd love to see the new Corvette (C7)

    Also you could consider some older cars. Especially 60's-70's muscle cars.

    I find the lambo's and the like quite boring. Also they do not much fit the concept of Traffic Racer.
    Wow, that C7 looks amazing. But I'm afraid it's also too fast for the traffic :)

    As for the muscle cars, yeah you are right. Eventually, I should add something old.

    How about a Porsche 911 or the original Audi Quattro (the UR I think it was ) or the Audi A8 V10, the current Nissan GTR, Mercedes AMG C63. Such a great game, thank you

    I've always thought Lambo's were boring too. First thing that stood out to me when I bought this game was the tasteful selection of cars, so definitely maintain that.

    And yeah I didn't think about the C7 being too fast. Lol

    1970 Dodge Challenger has my vote.

    I could live with any of those. Especially the GT-R. And an older (like the 80's) 911 would be sweet. Those would be too fast, though, as mentioned above.

    Quattro would work.

    I did some testing and the problem seems to be related to the device's orientation. Holding the iPad with the home button to the right (which is the position I prefer to play) the car tends to go left. With the home button to the left, the car keeps centered.

    Also tried it on my girlfriend's iPhone and on her mini iPad and got the same behavior (only with the home button to the right).

    Hope that helps.

    That's interesting. I will definitely look into that. Btw, do you see the same behavior in the games like Lane Splitter?

    I don't see this behavior in Lane Splitter, but it's difficult to compare, because you can't change the orientation and also it has a calibration feature (which I used).

    I also don't seem to have problems with games like NFS or Asphalt, but then again it's hard to compare the gameplay of those games to Traffic Racer. I think Traffic Racer requires much more precise controls :cool:

    But I did some testing with Multi Measures HD (https://itunes.apple.com/br/app/multi-measures-hd-all-in-1/id374844888?mt=8), using its "spirit level" tool and got some interesting results:

    With the iPad laying on a table top, with home button to the right, it reads an inclination of 0.5° while with the home button to the left, it reads -1.5º. Ok, suppose my table is not perfectly leveled, still it's a 2 degree difference on the reading, just because of the device's orientation.

    I was surprised to see that even that tool has a calibration feature, so I guess the iGadgets' sensors are not 100% precise. And more - if I hit the calibrate button in one orientation, it still gives me the same old reading in the other position. I need to calibrate it in *both* orientations (and apparently the app saves both) so I can have a 0.0º reading in both positions.

    Well, I hope I'm not confusing things even more. Thanks for your attention and support!

    I just happened to realize that the in-game odometer is not accurate. I noticed the distance was increasing too slowly for the speed I was driving, so I decided to check some data from replays.

    It's easy to see the discrepancy in this (awesome) video you posted earlier:

    https://everyplay.com/videos/695713

    He travelled 2.31Km in 100 seconds, what gives us an average speed of only 83,16 Km/h. That can't be correct, since he stayed above 100 Km/h during almost the entire run (97.3 seconds).

    Not that it changes anything in the gameplay, but I decided to point it out.

    Hvianna, thank you very much for sharing your observation in detail. I will add a calibration feature for the next update. As you said, the accelerometer input of some iDevices seems to be incorrect. Calibration is the only way to work this around. Also, thanks for pointing the effect of oriantation to the calibration. I will also save the calibarion offset for both orientations. Since this is my first game on the App Store, I still have lots of things to learn :)

    Yeah, the distance does not represent the real-life distance, unfortunately. But fixing it now will affect the leaderboards. So, I think it's better to keep it as it is.

    Awesome, thank YOU!!


    I understand. But score-based leaderboards are already affected by improvements you make to the game, like faster cars and things like the new double-overtake bonus, so I don't think it would be much of a problem.

    It could affect the game "economy" by giving out more in-game currency per run, but you could keep the old distance algorithm for calculating the cash grants, or just reduce the amount of cash per kilometer.

    Fixing the "economy" will be easy, but there is a leaderboard that keep "distance" traveled, which will be affected directly. All the distances in this leaderboard will be deprecated by a factor of 2 or 3, if I fix it :( That's why I'm a bit concerned about this.

    Hi again,

    Traffic Racer is now updated to 1.6.5. This is not a big one. But still you get a new car, and some improvements. Here is the list of changes:

    - Added 1 new car
    - Added accelerometer calibration
    - Overtakes in the opposite lane now gives 3 times more points
    - The models of some cars are updated
    - Performance optimisations
    - Minor bug fixes and improvements

    Thank you so much for adding the calibration! Controls are now perfect in my iPad!

    Love the new Pug 106! ;)
