Game developer use this image clips to form a complete frame, and build a animation for set of frames.
Motion Welder helps graphics artist to create animation out of such image clips. |

| Q |
What is .cpl file, and how to use it? |
|
| |
.cpl is the Image Clips file, so that one can export clips from one workspace to other. To import .cpl file, right click on Clips Image, and select Import Option.
Another usefull advantage of .cpl file is to store coordinates of character in a font file. Here is how you achive that.
Create .cpl file and store coordinates(X, Y, W, H) that your need, as you might not need all the coordinates.
For example, in your font strip, all the characters have constant height, so you just need to store (X, Y, W), and similarly check for other cordinates and optimise it.
Use MCPLReader to read .cpl file. |

| Q |
In Motion Welder Library , why are there two version of player to play animation, MSimpleAnimationPlayer and MSpriteAnimationPlayer, and which one to use? |
|
| |
Both MSimpleAnimationPlayer, and MSpriteAnimationPlayer are used to play animation, but only diffrence is the way they interact to play animation.
(I) MSimpleAnimationPlayer player = new MSimpleAnimationPlayer(animationData, x,y);
(II) MSpriteAnimationPlayer player = new MSpriteAnimationPlayer(animationData, mycharactersprite);
In (I) player accepts animation, and ask for where to play that animation, where as in (II), the location, orientation etc is pulled from mycharactersprite (MSprite) object.
In case where there is no requirement for a class for a sprite, use of MSimpleAnimationPlayer is preferred. And case where you have class for a sprite, use of MSpriteAnimationPlayer is preferred.

| Q |
Why i have to load image separately using MSpriteImageLoader, while loading animation in my game? |
|
| |
Motion Welder does not integrate images along with animation, and give freedom to developer, to select his own way of loading Images. As many developer prefer to load it directly from res folder, and some by mixing data and palette, or some would prefer to load it from lump of binary file of resource.
An interface MSpriteImageLoader in motionwelder library is used to load image. Please refer example/doc for more detail. |
