Tracing an onscreen line for touch devices

Hi everyone;

my team is making a Japanese language learning app for Android and iOS; and I would like the user to be able to draw a line onscreen to trace out a kanji character. There needs to be a line following the user's finger as he/she traces onscreen - the point being to learn how to write specific kanji characters.

Here is an example of what I mean in the second to last screenshot on this app:

play.google.com/store/apps/details

Is this possible in Construct2? I cant find any documentation on how to do this and am currently stumped. Thank you for any help!

I've don simular things

have a invisible bullet with a very high speed

set angle toward touch.x & touch.y

have a 10 by 10 sprite and set position to touch.x and touch.y

have the bullet speed 0 if overlapping the 10 by 10 sprite

spawn a circle dot the size you want the line if bullet speed is greater than 0

this will spawn a dot every tick the bullet is moving making it appear as a line

Thank you, I will give it a try!
