Speed up OPE... not what you think
I need an OPE animated object to speed up as it moves along its path.
I have no rotation and only 1 direction of motion. I linked the duration to a VDS with a Set Value Event to decrease the VDS.
If I set the decrease event to 60 (1sec) and the interval trigger controlling the SVE to 5secs I get a noticable glitch/frame jump every 5 seconds...
I tried reducing the Values to 1 tick equivalent but after about 45 seconds the frame was rattling around like crazy.
Any ideas anyone?
Edit, I have solved this, the interval controlling the decrease has to be set to 1 tick, I had the SVE set to 1 tick. I just turn off inputs when speed has reached the desired level.
Thanks for looking, I hope this helps someone.

Speed up? Curved Data Sources are for that.
Ease In is generally increasing speed from start to finish, there's just many different curves to choose from to set the rate of increase over time.
Sine curve is closer to Linear, slight increase over time while Exponential is really steep near the end, so it increases in speed a lot mostly during the last half of the timer.
To have a visual clue:

If it's 1 direction of motion you can either use coordinates (global movement XYZ start to XYZ finish) , or just simpler local movement via 1 axis with a set time/distance.

Thanks Teri, sorry for the late reply.
All the curves in the cds had either too slow or too fast starting curve. what I eventaually achieved is a way to flatten out the curve in the middle to maintain a constant(ish) speed for a while.
It worked mostly ok except when its duration is reduced again (i had some juddering), I think this method could work better with more use and lots of tinkering.
The track I made is called Training Session and its in TC on 360... oh yeah its a skill game in case I hadn't mentioned.
Edit; I just re-read my first post and I wrote VDS instead of CDS.... I now understand the confusion.
