Start.motion

The start.motion command sets a screen object's movement mode to 'normal', and if the object is ego, also sets the ego to player control mode.

Syntax

start.motion(obj oA);

Remarks

This command sets screen object oA's movement mode to 'normal'. If the screen object is the ego object (o0) it also switches to player control mode.

This command is identical to the normal.motion command, except that it also switches ego to player control mode. The normal.motion does not automatically switch ego control mode.

Possible Errors

AGI does not check that object number oA is a valid screen object. If it is not, this command will overwrite other data on the memory heap, which may cause unexpected results, including possibly crashing AGI.

Example

Code:

<syntaxhighlight lang="agi"> stop.motion(ego); [ ego stops moving, and switches to program control start.motion(ego); [ equivalent code normal.motion(ego); player.control(); ... [ for non-ego objects these two lines do EXACTLY the same thing start.motion(o1); normal.motion(o1); </syntaxhighlight>
