Hey all. I was thinking about the recent Radar animation and I thought it would make a good tutorial.
Whether I am able to do it justice is another matter!
Ok, firstly I must credit the original static tutorial creator.
The original can be found
HERE authored by Chris G.
I didn't follow this tutorial word for word, though you might like to.
Because I was working with the thought of an Avatar image for ATS in mind I created a new image 160 x 160 with a transparent background. I set my
foreground colour to the green that radar brings to mind. And the background to black. (Obviously though there are numerous times throughout this
where you could alter something to suit your own tastes.)
Select the paintbucket tool, (G) Then press X (which swaps the foreground and background colours) and fill your square. Double click on the layer
panel (bottom right) and rename this from Layer 1 to Background.
Create a new layer and name this one Arm. Click on the paint Bucket Tool Icon and select Gradient Tool. Press X to swap the foreground/background
colours again, making our Green the foreground. Click on the Gradient Picker window (top left) and select Foreground to Background. To the right of
that window there is a slection of five icons for differing styles of gradient (Linear, Radial, Angle, Reflected and Diamond) choose Linear gradient.
Left click in the top left of your image (making sure you are still on the Arm layer) hold and drag diagonally toward the bottom right untill you are
just over half way. Now from the very top toolbar go to
Filter -> Distort -> Polar Coordinates
and select the Rectangular to Polar option.
In the Layers panel click the Create a New Set (folder) icon and drag both your Arm and Background layers into this 'Set 1' folder. You should now
have something like this:
In the Layers panel, make sure you close the 'Set 1' folder (the little triangle arrow next to the folder icon) then create a new layer. Name
this layer Overlay. Open the Marquee tool flyout (top of the left hand side toolbar) and choose Eliptical Marquee. Our image is 160 x 160 so with the
rulers up (Ctrl + R) and the units set to Pixels (right click on the ruler to set units) we can see when our Marquee crosshair lines up perfect
center. Holding down Shift+Alt left click and drag out to make a perfectly circular selection. Drag it out so the selection is about 10px shy of the
edges. Using the paintbucket tool fill the selection with the Green from earlier. Keeping that now Green circle selected (if you have accidentally
de-selected then just Ctrl-click the layer) Go to
Select -> Modify -> Contract
and contract the selection by 1 pixel, then cut out the remaining selection (Ctrl+X).
Duplicate this layer (don't worry about naming the duplicate) then go to
Edit -> Transform -> Scale
Up on the top toolbar change the width and height to 80%. Duplicate this new layer, and scale it to 75%. Duplicate again and scale to 65%. In the
layers panel you should now have four 'Overlay' layers. Keeping the top layer selected press Ctrl+E to merge layers down untill you are left with
only one 'Overlay' layer. You should now have a basic Radar layout something like this:
To this you can add whatever further decoration you desire, crosshairs, coordinate text etc. Just remember to keep the Overlay background
transparent.
Now we get to the fun part - Animation.
Save your .psd image and open it up in ImageReady. In the layers panel go into Set 1 and select the Arm layer. Next, in the same window as the
Layers panel, click on the Actions tab bringing it to the foreground then scroll to find and select Spin. With Spin highlighted, click the 'Play
Selection' button as the bottom of the panel. Now you should see something like this:
If it is not up get the Animation slideshow window up by Window -> Animation. In this window, set the looping options (bottom left in the Animation
window) to Forever. Now click play in your Animation slideshow window you should now have a nice rotating radar.
Now to give it some signals!
Create a new image in ImageReady same size - 160 x 160. In the Animation window duplicate the current (empty) frame. Select the first frame.
Select the paintbrush tool and place a dot wherever you want to recieve a radar signal from (here I chose six O'clock). Now in the Animation window
select the second frame, then go to the Layers panel and toggle the visability (of our one and only layer) to off. In the Animation window select
Tween... Use these settings:
Tween With: Previous Frame
Frames to Add: 4
Layers : All Layers
Parameters: Position, Opacity and Effects. (All selected)
Now, if you click Play in your Animation window, you should see your six frame dot animation blinking:
Now, we have both images (blinking dot and Rotating Radar). With our new blinking animation selected, left clicking on the arrow in the grey bar in
the top right of your Animation window should bring up another fly-out menu:
From this menu go 'Select all Frames'. Then open it again and 'Copy Frames'
Now select the Rotating Radar animation. Click on the frame you wish your signal to appear in first, for this example I have used six O'clock, so
in my Animation window I would click on frame 7. Now if you then Shift-Click the last frame you want your (faded/fading) signal to appear in you will
select up to that frame inclusive. For example I Shift-Click 12, so have selected all frames 7 to 12:
Now open up the same fly-out we used to copy the frames and select 'Paste Frames...' In the pop-up box that appears, select 'Paste Over
Selection'.
Now in your Animation window (again with the Select looping options set to 'Forever') you can preview your Animated Radar with it's signal:
And there you go, add as many signals and radar screen decorationas you wish.
I hope this has helped someone get to grips with ImageReady a bit better. (It is my first ever tutorial)
