multiple linear() expressions in a row
hey guys
i have a slider and several position keyframes (on a null). now i want to move from key(1) to key(2) when slider slides from 0 – 25 … no problem … but from 25-50 it should move from key(2) to key(3) … okay second linear() expression… i multiplied it all like this:
s = effect("Slider Control")("Slider");
p = transform.position;
linear(s,0,25,p.key(1),p.key(2))+
linear(s,25,50,p.key(2),p.key(3))+
linear(s,50,75,p.key(3),p.key(4))+
linear(s,75,100,p.key(4),p.key(5))
so i summarized the linear expressions together but then my null goes crazy like all the key() get summarized :-/

See if this works for you:
s = effect("Slider Control")("Slider").value;
if (s <= 25){
t = linear(s,0,25,key(1).time,key(2).time);
}else if (s <=50){
t = linear(s,25,50,key(2).time,key(3).time);
}else if (s <= 75){
t = linear(s,50,75,key(3).time,key(4).time);
}else{
t = linear(s,75,100,key(4).time,key(5).time);
}
valueAtTime(t)

sweet ☺ tried something similar with if/else conditions but didnt know about doing it with t=linear(…. and valueAtTime(t) ☺ this works great! thank you
