4.6.2 New (Ctrl+N) -> choose resolution and enter
|
Limitation: A.) Look in Layers panel (Maybe in right hand) !!! MUST DELETE BACKGROUND LAYER BEFORE!!! B.) Doesn't support vector shapes and layer style directly, must rasterizing save before. |

4.8 Script
|
Script must write after layer name e.g. Layer name is boss, click in layer and rename it by double click or menu Layer -> Rename Layer... |
4.8.1 Transformation script, Pivot, Rotation and Scale
A.) Pivot, value start at top left of layer position, user can check in Photoshop layer info.
|
<layername> f=flags flags: c = center l = left r = right t = top b = bottom h = horizontal flip v = vertical flip d = default is l|t every flags can or bit e.g. boss f=r|b|h |
B.) Rotation
|
<layername> r=0x0x0 rs=speed r= rotation axis x y z, value is int 0 mean static, > 0 mean dynamic rs= rotation speed, value is float speed is more value then sprite is spin fast Rotation must available both r and rs in same time. e.g. boss r=0x1x0 rs = 50 |
C.) Scale
|
<layername> sc=1x1 sc= scale in x and y, value is float, 1 mean normal, > 1 mean large, < 1 mean small range of scale 0.01 to 2. !!!Scale can't be 0!!! e.g. boss sc=0.5x1.5 |
D.) HUD script
|
<layername> hud hud (lower case) is script tell ARSA Framework for draw HUD. HUD is Head Up Display if set sprite draw on the top always. e.g. lifebar hud |
4.8.3 Reference script
Use often when artist create map as tile or artist need reuse sprite benefit of them is reduce memory allocation.
NOTE: Try google search 2d tile map for additional information.
|
<layername> aref=<layer_ref_name> aref= rederence, value is string, <layer_ref_name> is original layer name. Original layer name have not space. e.g. boss2 aref=boss |
4.8.4 Animate script
User can create animation sprite in Photoshop by following script.
A.) New layer and set start script.
|
{ |
B.) Create image or layer after that. Create frame sprite as normal procedure.
C.) New layer abd set end script.
|
} name=<your_name> fps=speed loop=loop_flags play 1.) name=<your_name> value is string, name of animation 2.) fps= animation speed, value is float if value more animation is fast, 0 is freeze 3.) loop=[loop flags] values are: true= loop all the time, once = do 1 time, pp = pingpong playing animate, default is true and flag can orbit. 4.) play if specify this keyword animation will automatic playing after loaded psd. |
D.) e.g. animate script
|
{ boss003 boss002 boss001 } name=boss fps=30 loop=true|pp play |
NOTICE:
Easy and clean manage layer, User can group all animation layers to single group.
4.8.5 Configuration script
New layer and rename to below script
|
screensize(W,H) screensize= force draw sprite to custom screen resolution W = width, H = height ARSA Framework will draw .psd on any device by force to that screen resolution, benefit for universal app. value is int. Example: screensize(960,640) |
|
maxsize(X,Y,W,H) maxsize is a command specify min/max boundary size when scroll sprite. X, Y is min, W,H is max size. value is int. Example: maxsize(0,0,960,640) |
|
setoffset(X,Y) offset is a command start all sprite offset in this psd file. value is int. Example: setoffset(0,0) |
