#!F-adobe-helvetica-medium-r-normal--18* #!N #!CSeaGreen #!N #!Rvcrcomm Sequencer #!N #!EC Data Explorer provides the following commands that allow you to control the Sequencer. You can use these commands in a script or by typing them to the executive. #!N #!I0 #!N #!N #!Cnavy #!N #!I0 #!N sequence #!EC #!N #!I50 #!N The sequence command defines the frames that you specify in the Sequencer variables using the images supplied by a function call or expression. The following table defines the Sequencer variables: #!N #!N #!T,1,141,211,281,631 #!F-adobe-times-bold-r-normal--18* TAB Name TAB Read Only TAB Read/ Write TAB Description #!EF TAB @deltaframe TAB - TAB x TAB The number of steps between frames. TAB @endframe TAB - TAB x TAB The index of the last frame. TAB @frame TAB x TAB - TAB The index of the current frame. TAB @nextframe TAB - TAB x TAB The index of the next frame. TAB @startframe TAB - TAB x TAB The index of the first frame. #!N #!T,0 #!N #!N In the following example, the sequence command defines eleven frames for the Sequencer. These frames can be displayed using other Sequencer commands. #!CForestGreen #!N #!N #!F-adobe-courier-bold-r-normal--18* #!N . . . #!N @startframe=0; #!N @endframe=10; #!N @nextframe=@startframe; #!N sequence displayobject(20*@frame); #!N . . . #!EF #!N #!N #!EC #!Cnavy #!N #!I0 #!N play #!EC #!N #!I50 #!N This command begins execution on the frames that have been defined with the #!F-adobe-times-bold-r-normal--18* sequence #!EF command. #!Cnavy #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* pause #!EF #!EC #!N #!I50 #!N This command stops the sequence at the current frame. #!Cnavy #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* step #!EF #!EC #!N #!I50 #!N This command displays the next frame in the current sequence direction. #!Cnavy #!N #!I0 #!N #!EC #!F-adobe-times-bold-r-normal--18* stop #!EF #!N #!I50 #!N This command stops the sequence display and returns to the first frame in the sequence. #!Cnavy #!N #!I0 #!N #!EC #!F-adobe-times-bold-r-normal--18* forward #!EF #!N #!I50 #!N This command sets the forward direction of the sequence. #!Cnavy #!N #!I0 #!N #!EC #!F-adobe-times-bold-r-normal--18* backward #!EF #!N #!I50 #!N This command sets the backward direction of the sequence. #!Cnavy #!N #!I0 #!N #!EC #!F-adobe-times-bold-r-normal--18* 'palindrome on' #!EF #!F-adobe-times-bold-r-normal--18* off #!EF #!N #!I50 #!N The palindrome command with its parameters sets or unsets the palindrome mode. When you display frames in the palindrome mode, the current direction changes at the first or last frame in the series. #!Cnavy #!N #!I0 #!N #!EC #!F-adobe-times-bold-r-normal--18* 'loop on' #!EF #!F-adobe-times-bold-r-normal--18* off #!EF #!N #!I50 #!N The loop command with its parameters sets or unsets the loop mode. When you display frames in the loop mode, the series of frames repeats using the settings of the forward, backward, and palindrome commands. #!I0 #!N #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lfilincl,dxall550 h File Inclusion #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
