Post subject:  Var_Curve or Motion Prediction Issue

Greetings,

I am having an issue where the 95% awesome ability of Chaotica to draw a nice curve given three points is not working out for me. I wish to follow another iterator linearly to a certain point, and then veer off linearly to another point triangularly (or just angular). However I get a very nice curved projection, using the three points, that I don't want. Is there a way to change this in the script (another variable other then "var_curve" like "var_line"?

Just wondering as it would make my life easier at the moment. :)

Thank you.

As a side note:
This would also be nice if you wanted to hold a value without moving for say, 0 60 and then start moving from 60 to 90 and hold another value static.

A line is also a curve, so don't think any name change would happen ^^

Currently, only smooth interpolation is possible, but there is a hack that may help you: you can just force it to look the way you want by setting extra keyframes (for example, around the turning point, one keyframe for each frame, with the desired values).

Example of the hack
you have a 60 frames animation, and have a parameter that you want to go like this:
1 from frame 0 to 19
increase in a straight line from 1 to 20 from frame 20 to frame 39
remain at 20 from frame 40 to frame 59

To achieve this, you set the following keyframes:
frame - value
0 - 1
17 - 1
18 - 1
19 - 1
20 - 1
21 - 2
22 - 3
25 - 6
29 - 10
34 - 15
38 - 19
39 - 20
40 - 20
41 - 20
42 - 20
59 - 20

Awesome I'll try it out. I'm using this to hide an iterator, and stealth it with another until a certain time frame. This might be what I needed. Since I need to go in a straight line for 2700 frames this might be a novel. :)

Works pretty well for specifically that purpose.
Although, for large animations, i suggest doing a notepad hack instead of editing the values directly in chaotica.

I found another way. Simply make two files one with the iterator and one without. Then splice the one with the iterator in when you want it. That's only if you want to stealth an iterator, which is not normal anyways. Your way however proved very useful I finally got that darn animation to do what I wanted.
