[quote:21s5xrmq]This is confusing more than helping. Please have a look at my long post about it. There are two variables that are related to each other and influence each other. Also, my expression never reaches frame 0, I think it is a better way to make sure you don't get unwanted values instead of hoping that Construct will catch the error.
What ever.
Still say it's a better way. He just needs to get the value of the variable before he even thinks about setting the frame.
Then there's the lerp method. You can use 1-10, 1-11, 5-20, and change the modifier to n*0.1.
And if your terribly worried about returning a zero, all you have to do is change the always condition to a comparison making sure its greater than 0.
