Start each objects movement individually

[elvisish]

I have some items I want to move up and down, but I want them to be triggered at the start of frame to start sequentially so they are all at different stages of the path movement to add visual variety, how can I use the "for each" to start each objects movement sucessively one after another? I'm using path to move the object up and down, sinewave didn't seem to be able to use relative amounts?

You can do it in different ways, an example could be:

1) start of frame >>> spread value 1 in an alt. value of your objects

2) alt.value = timer / 1000 >>> start movement
(this will start them sequentially, one each second)

You can change the parameters of a sinewave movement during runtime with the "clickteam movement controller" object
(I just discovered this few months ago... thanks mobichan!)
or you can use a custom sinewave movement if you want additional control,
it could be easy depending on what you want to do

i.e.

start of frame
>>> set alt. value Y to Y(object)

always
>>> add sin(timer) * 8 to alt. val. Y
>>> set Y position to alt. val. Y

to slow down/accelerate the movement
or increase/decrease the distance moved,
divide "timer" by some amount or multiply sin(timer) by some different amount

Thanks @schrodinger, that makes a lot of sense, I haven't tried the CT movement controller yet, just had a look at sinewave. Do you have an mfa file that would examplify this? I've tried value spreading in the past and I usually screw up when I try!

[schrodinger]

Here's a quick example of things mentioned in the post above:

timed_sw.mfa

Spread value will simply put an incremental value, starting from the number you spread, in each instance of your object
so that if you have 5 objects, and you spread value 1, your objects will have individual values of 1,2,3,4,5

[elvisish]

That's perfect thankyou! Is there a way to slow down the speed of the sine?

[schrodinger]

yes, you can divide "timer" by some amount,
this will also stretch the range though,
so you would have to divide the distance also if you want to keep a similar movement range

i.e.

Sin(timer) * 15

can become:

Sin(timer/2.0) * 7


You could also use a value instead of "timer"
and add to that value with the timing you prefer
so you can alter the speed however you want

[elvisish]

That works spot on for the speed and height, now I've tried this with a qualifier, I've converted the flag to using Alt value B as I'd rather use Alt values than flags, but all the objects are moving at the same time, it seems this only works with objects not qualifier groups?

[elvisish]

Also, each object that's offset sines higher or lower than each other, is there a way of having them look more like they're at different stages of the sine rather than being moved higher or lower with the same sine?

I would personally ditch using the actual Fusion Timer and instead opt for an alterable value that increases by 1 every frame and wraps at 360. You could easily set it to tick and wrap with an always event like so:

Set value to (value+1) mod 360

Then you could simply set the value to be whatever you want at start, and it'll begin at that position in the sinewave.

I know it's clique, but could you whip me up a quick example, I've not used mod before! :/
