Ok I know this is unconventional but since I don’t know unity or anything else but I do know quite a bit about unreal so I decided to go forth with it…
I am currently facing problems in alphabet tracing. I am envisioning a stencil of the alphabet that the kid can color inside.
I have a stencil ready but am confused as how to colour in between the gaps(the stencil is a sprite)
Any help or ideas would be awesome
thank you
So you want a kid to color the letters in at runtime?
If you want to do a bit of research, this seems like something you could do with render targets. I’m not knowledgeable enough to say how, but I know I’ve seen them used for things like this.
Unfortunately, I tried that and it won’t work because this app is to be released for mobile and the render target(at least the tutorials I followed I’m not skilled enough to make it to fit my project 
) used where the camera was pointing so that means that ill need a script to look around which, to say the least, would be unideal for a linear app like I’m planing.
I rather thought about using decals that will spawn when the kid goes over this area and the area would be in the shape of the letter.
However, I can’t seem to implement it but don’t know how to any help you could provide me, in this case, i would be so grateful.
I want to help you. I’m working in an University in Spain in proyects of education and I learned UE4 just for that. But I’m not very good at english so let me know…
What’s exactly what you want to do? An APP for Android where a kid color inside a letter path/stroke? as the painting books?
Or is more like a calligrapgy notebook?
Thanks!
-No exactly like a coloring book only the app dictates what area he colors first the letter and of course he colors with his finger by dragging it inside the lines.
I am now thinking to do something w/ decals like if he drags his finger along this area this decal will spawn but I have no clue as to how effective I also don’t know or how to do so
Again Thank you for any help you can provide
