Arw_SetSize returns a value of 0 if the size was successfully assigned, and a value of -2 if the specified object ID number is invalid. | |||
== | == Usage == | ||
<syntaxhighlight>Arw_SetSize(ObjectID, ArrowSize)</syntaxhighlight> | |||
Where: | |||
:'''ObjectID''' - a numerical expression specifying the object ID number. | |||
:'''ArrowSize''' - a numerical expression specifying the arrow size. | |||
== 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. | |||
== Example == | |||
Assign an arrow size of 10 to the arrow object with an ID number of 3: | |||
<syntaxhighlight>Value1 = Arw_SetSize(3, 10);</syntaxhighlight> | |||
