jit.anim.node jit.anim.drive

 Quick overview of jit.anim.node and jit.anim.drive

 How do we move things in jitter? You could specify the @position/rotation/direction on a gridshape itself & perhaps attach variables to them. Totally valid, but the intended way to move things, or animate things is to use the jit.anim.node and jit.anim.drive.
The benefits  of using these two nodes is that you get to make hierarchical transformations.
Eg. A parent node might move from left to right, whilst the child node inherits this horizontal motion whilst it rotates & moves up and down. This allows for some nice modular kinda motions.

Jit.anim.drive we saw before, can be used to move things around with our mouse and keyboard input. It is possible to change the mapping of this node by first double clicking on it whilst the patch is locked (or holding ctrl then double clicking) - copying the contents of the file that opens & then pasting/making changes to it in another "dictionary", which you would create by hitting "n", then typing "dict" followed by a name for your dictionary. eg. "n myDict".
I think I'll go into dictionaries and implementing this a bit more in another post. 

Thing to note - if you need something to be a float, always always remember to add a . after a number. Eg. 0. 0. 0. if you were setting the default arguments for something. 

 Here's an example of using jit.anim.node and drive to make the torus wobble.

 

I'm using a send + receive metro, from the jit world to generate bangs.. This then goes into a "counter", which can be reset if you wish. The counter outputs into a "float" node, to "convert" it to float type, which then gets fed into a sine node. I then multiply the resultant sine value by 10, and then "pak" this value into the Y of a vector. I've left the X and Z as value zero.
This pak is useful because it spits out the list (x y z values) everytime any input is updated. It goes into a message node with the "rotatexyz" message and the variables $1 $2 $3 - which the pak'd values substitute.

That message is then passed into the jit.anim.node, which is also scaling  the gridshape uniformly by 0.5.
It should be noted that anim.node and anim.drive both override whatever you hardcode into the gridshape node. It will ignore all transform attribs.

Notice that I plug in the jit.anim.drive above the anim.node because drive is *always* the parent. It can't be a child, apparently. With this you can move the object around with your wsadqz keys and the wobble will be applied after that.

Compressed-patch - should be able to copy and paste this!

displaying a jitter movie

one way of loading a movie file is to use the "jit.movie" object, with a few parameters.  jit.movie @vol 0 @moviefile bball.mov the @vol 0 reduces the volume to zero, sometimes you don't want the audio from your video file @moviefile specifies the file. bball.mov is a built-in movie file. You might have a full path, or even a file on the desktop. eg. Desktop:/myname.mov  The jit.movie object also needs a way to display - use a jit.pwindow. Plug the left output into the pwindow's left input. You'll also need to bang the jit.movie to update the pwindow! You could plug a button (b) into the jit.movie and keep pressing it......... But this is going to be annoying to do manually, so we can use a "metro" object (which is metronome) and specify how often we want to send a bang message. This is measured in milliseconds. To achieve 30 fps you'd use a value of 33. Because 1000/30 = 33.3333333333 So, hit n, type metro 33 then have that connected to the input of...

load texture using path

  This is supposed to be a fast and automated way of loading textures into the jit.gl.texture... Honestly... it would be far quicker to drag the images onto the object as mentioned in the previous post, but I guess it is worth mentioning the "this patcher" object which provides the path for where the patch has been saved (displayed using the message object). It seems like you have to pass it a "path" message for it to output the info. Next we use sprintf to add the rock/Rock..............etc to the end of the path. I believe the %s represents the string that you pass into the sprintf object, eg the path. The symout is present to process any symbols or spaces as text. Prepend adds the "read" message in front of the full path of the texture file, this gets piped into the jit.gl.texture and when banged the texture should be loaded in. You might find you have to click some of the upper bits of the path to trigger it all. I find this method a bit extra, but I d...
