Thanks for your reply.

I know that bullet already use delta time. What I want to say is it doesn't make any difference whether I use bullet, or try to set the position of object by using delta time (of course not implementing both at the same time). And the problem of jaggy movement only happens when export as a mobile app, it runs very smoothly on the browser in remote preview.

So you did not experience any jaggy movement when exported as a mobile app? Is there any app you have published that I can download to try?

I made a simple example that clearly demonstrate the difference in the smoothness of movement between remote preview in browser and exported as mobile app.

What is your view on this? As you are a strong advocate in remote preview, there must be something wrong if their performance (not in fps, but the smoothness of movement) differ so much.

I try to use the bullet behavior, which does the job well on a browser and when in remote preview. But when I export the project to Android, the movement becomes jaggy. The fps remains at 59-60 but the movement is just very rough.

You can try to reproduce it by having two sprites, each 250x250, and set bullet speed to 400. It doesn't matter whether the bullet speed is large or small and the browser can have smooth movement, only when it is exported as a mobile app the movement becomes jaggy. I also tried to update the position by using every tick, update Object.Y to Object.Y + speed*dt, but same result (smooth when viewing in browser but jaggy when exported as mobile app). Any ideas on what's happening and how to solve this?

I found this thread on Unity and am not sure if it is related. Any help would be appreciated. Thanks.

I tried it with a very simple program that several sprites of size around 250*250, have bullet behavior that moves at speed 1000, gets 60 fps and pretty smooth movement on browser. But once I export it as an android app using the Construct 3 built, still get 60 fps but the objects now "flicker" (not sure if it is the correct word, but the movement is a bit choppy) when moving, even when the bullet speed is set to something small like 400. Anyone has similar problems before and a solution to fix that?

Yes, the C3 splash screen will show up in mobile app if I choose the loader style to be C3 splash.

I try to do everything in C3 (using its build service to produce unsigned apk) and I don't know where I can find the splash screen files, because there is only a single c3p file for the project and there is not much in it. Not sure if the splash screen files can be located/replaced when using other build service such as phonegap or not.

I tried that, with the loader layout containing only a 250x250 sprite, but it still takes maybe 1-2 seconds before that will show up. The C3 splash can show up instantly, and I believe for iOS xCode project, we can change the splash screen. So I am wondering if we can do the same for android app or not.

It also said that we may want to focus on custom splash image for native apps in the limitations section.

Anyone has any idea on how to do that? If it is listed as one of the main features, it shouldn't be hard. Any help please?

I am wondering if there is indeed this feature, but it is clearly listed here.

One of the benefits listed under personal licenses is "Custom splash screens", but in loader style I only see the option of choosing Construct 3 splash. Where should I upload my custom splash so that the game (exported as native mobile app) can load with my own splash? Thanks.

In the system expressions

MyVar = zeropad(1,99)

Replace(MyVar, 0,1)

Thanks!

Say I want to generate a string 111...1 (say 100 1's). I can do it with a for loop, just wondering if there is any simple expression to do that instead. Thanks.

Is there any difference in performance if I use a number variable with value 0 and 1 versus a boolean? What are some advantages of using boolean instead of number variable? Thanks.

Thanks, that's helpful and I think I figure out how to do that now.

Maybe I did not ask my question clear enough. What I want to achieve is when the user clicks on the "twitter button", he will be directed to an url such that a message has been pre-filled and the user just has to confirm whether he really wants to tweet.

In the thread of FAQ, Kyatric suggested some URL like
