I'm currently working on a project which requires to have text displayed along a curve. If found this entry a good starting point. It works fine for me on my develompment machine, however the customer on his machine noticed some issues.
The basic idea is to define a path for the text, explode the text into the separate characters and animate them along the path the fraction of the character of the whole lenght. So with a animation duration of 10 seconds and a label of ten characters, the first character would be animated along 1 second, the second 2, and so forth.
This is done by jumping to the designated time in the animation, start the animation and stop it imeadiatly.
Now the problem as I see it, for stopping the animation a separate timer is used, so it can happen that at the time the animation is actually stopped, the animation moved further than the first frame. The effect is that the last characters of the text appear in front (wrapped aroud).
As I have no evidence to prove or disprove my theory, what do you think is this plausable?
I can see a workaround for this issue by defining a path for each character and then let the animation run to the end. While I can set the duration of the animation to 1 ms which should not be visible to the human eye, I'm not able to make the characters invisible and turn the visiblity on when the animation finishes, they always become visible at the start.
Another idea still more complex would be to create my own animation/transition for placing the characters.
Do you see any other possibilities?
