Arw_GetColor returns a value of -2 if the specified object ID number is invalid. | |||
== Usage == | |||
<syntaxhighlight> | |||
Arw_GetColor(ObjectID) | |||
</syntaxhighlight> | |||
Where: | |||
An object-specific ID number is | |||
:'''ObjectID''' - a numerical expression specifying the object ID number. | |||
== | |||
Assign an RGB color number, corresponding to the color of the arrow contained in an arrow object with the ID number of 3, to Value1 variable: | == Notes == | ||
* An object-specific ID number is assigned by [[Arw_New]], [[Arw_New_s]], [[Arw_New_self]] or [[Arw_New_self_s]] when the arrow object is created. | |||
* Use [[Arw_GetActive]], [[Arw_GetFirst]] or [[Arw_GetNext]] to get the object-specific ID number of an already created arrow. | |||
* Use [[Arw_SetColor]] to set the color of a specified arrow. | |||
