Action Flash Version: 

Pop a value from the stack representing the new property value.

Pop the name of the property to be changed. Note that the property scheme is from version 4 and as such the property name can be represented by a number. Older version actually only accepted floating point numbers.

Finally, pop the name of the object where the specified field property is modified.

The following is the list of currently accepted properties or fields for the Get Property and the Set Property actions. Note that the properties can be specified with either an integer (type 7, requires V5.0+) or a single precision floating point (type 1, V4.0 compatible). And since strings are automatically transformed in a value when required, one can use a string to represent the property number (type 0). It works with a double value, I even tested a Boolean and null and it works. Obviously it isn't a good idea to use these. The default should be a single precision float. Please, see the Push Data action for more information about data types.

WARNING: Adobe is trying to phase out this functionality. It is very likely not working in ABC code and it is not necessary since objects have member functions that can be used for the exact same purpose and it is a lot cleaner to use those instead.


Float Decimal Name Comments Version
0x00000000 0 x x position in pixels (not TWIPs!) 4
0x3F800000 1 y y position in pixels (not TWIPs!) 4
0x40000000 2 x scale horizontal scaling factor in percent (50 — NOT 0.5 — represents half the normal size!!!) 4
0x40400000 3 y scale vertical scaling factor in percent (50 — NOT 0.5 — represents half the normal size!!!) 4
0x40800000 4 current frame the very frame being played; one can query the root current frame using an empty string ("") as the name of the object; note that the first current frame is number 1 and the last is equal to the total number of frames; on the other hand, the Goto instruction expects a frame number from 0 to the number of frames - 1 4
0x40A00000 5 number of frames total number of frames in movie/sprite/thread 4
0x40C00000 6 alpha alpha value in percent (50 — NOT 0.5 — means half transparent) 4
0x40E00000 7 visibility whether the object is visible 4
0x41000000 8 width maximum width of the object (scales the object to that width) 4
0x41100000 9 height maximum height of the object (scales the object to that height) 4
0x41200000 10 rotation rotation angle in degrees 4
0x41300000 11 target return the name (full path) of an object; this can be viewed as a reference to that object 4
0x41400000 12 frames loaded number of frames already loaded 4
0x41500000 13 name name of the object 4
0x41600000 14 drop target object over which this object was last dropped 4
0x41700000 15 url URL linked to that object 4
0x41800000 16 high quality whether we are in high quality mode 4
0x41880000 17 show focus rectangle whether the focus rectangle is visible 4
0x41900000 18 sound buffer time position (or pointer) in the sound buffer; useful to synchronize the graphics to the music 4
0x41980000 19 quality what the quality is (0 - Low, 1 - Medium or 2 - High) 5
0x41A00000 20 x mouse current horizontal position of the mouse pointer within the Flash window 5
0x41A80000 21 y mouse current vertical position of the mouse pointer within the Flash window 5
0x46800000 16384 clone this flag has to do with the depth of sprites being duplicated 4
