Today's Lesson: "Animation"
Ok, So.. I lied. Well I
didn't Lie, I really was done, but this one was really simple and I saw some
people asking about this, and I had just finished making just this thing.
I figured why not.
So call it a bonus for me becoming a Master.. or call it, I was bored.
We will be Using the SCRIPTED Animation check you have seen in the Object "Animation" tab.
For this and all the Step-By-Step DX Tutorials you will need to purchase DesktopX for $14.95 from Stardock.
Lets get started.
STEP 1 - Create the objects
We are going to make a single object here, but its more complicated then normal.
First thing you have to do is make a PNG that has multiple images inside it. There are a LOT of ways to make this kind of PNG.
I have used FLASH to export a
series of images, then they all need to be complied into one image.
The trick with the frames
(objects) in this kind of image is that the need to be EXACTLY The same size,
and they have to be spaced EXACTLY the same as well.
In this case the image has 4 frames, I numbered them for you so you will be able to see the animation in action.
Create a NEW object, call it
"TEST" or whatever.
You can (save-as) the above image, and use it for testing. The Catch here is make sure you change the ANIMATION TAB in the STATES tab of the properties to show:
(4) Frames, and SCRIPTED is checked.
STEP 2 - Moving Ahead - Add a Script
Create a SCRIPT on the object we just created.
Lets look at the above script.
First we use the same function we use all the time to handle click:
Here is the main part of the
script. The script looks at the object to see what its Current Frame is.
CurFrame = object.CurrentFrame + 1
This is based on 0-3 not 1-4, even though there are 4 frames in the animation. We START at 0 not 1!!!!
Then we check to see if CurFrame
its less than < the max number of frames (4 frames of animation).
If so, then we make the current frame the new CurFrame.
Or else the object's CurrentFrame is set to 0 (the first frame of the animation).
So, that's about it. you
click on the object, and it changes the current frame up 1 each time till it
gets to the last frame, then it goes back to 0.
I used this in something I'm working on right now.
I hope you took the time to enter the code (not just copy/pasted the entire thing) so you could work thru the tutorial step-by-step and see how things work.
This one was very simple, but I know I didn't know how to use this till I had to, so I hope it helps everyone out.
This REALLY will be my last tutorial for a while. I hope you have enjoyed this step into DX.
