Graphics

A scripting question - I have created a bar chart and I can adjust the scaling (width) of the bar with the code below.

dim bar as xpBaseObject

scene.GetObjectByName("Bar1", bar)

bar.scaleX = cInt(text)/100

I was asked if I could then animate the bar. I'm currently faking it using a mask that animates. I was wondering if you can take the scale value and assign it to (or create) a keyframe.

I also work in the VizRT world and you can name keyframes in that timeline and assign values (scale, time, position, etc)

Thanks!

Brian,

have found the easy way to do this is place the object you are scaling inside of a group object. Then animate the scale of the group from 0 to 1. That animation will stay constant while the bar inside is scaling based on your script.

ok, thanks Andrew. I'll check that out.

Hi Brian,

You can do that without any problem.

Just create a cylinder with a length of let's say 500.

Change the Pivot-X to 250 (half of the length)

Then create keyframes where you change the value of Scale-X.

Done!

The only tricky part is that you need to do some math to calculate the scale when you are using numeric values. So if you have a bar displaying percentages. 100% would be scale 1. 0% would be scale 0. And percentages are the easy ones :-) It's when you have to use actual values where it gets a bit more difficult :-)

Best regards,

Thanks Kenneth. I think we're essentially doing the same thing. My question however was more on the animation controller. Say I set 2 keyframes, one at "0" where scaleX = 0.0 and a second keyframe at "20". I was looking for a way to tell that second keyframe what the scaleX value was going to be based on the value I entered.
