Showing trace when condition meets
Answered
Hi.
I want to draw a trace of a moving point which has same length from two fixed points.
I have tried to write script OnUpdate as " If(a==b,SetTrace(P,true),SetTrace(P,False)) ". But nothing show out. So what can I do now ?
Thanks in advanced.

I use an auxiliary point for this, with trace on always, but only shown when the condition meets. So I have to write a condition to show a point and not to show a trace. Doing so, I even give the trace another color then the original point. In the file added you can drag a point P and a point PP=P with trace on is only shown when absolute value of the difference between the distance to points A and B is less than 0.1 (to build in a slight margin). Of course you can play with this margin and/or the pointstyle of PP
