Observe.objs

The observe.objs command prevents a screen object from moving through other objects.

Syntax

observe.objs(obj oA);

Remarks

If screen object oA was previously set to ignore other objects (using the ignore.obj command), the observe.objs command restores normal behavior.

Use the ignore.objs command to allow an object to pass through other screen objects.

Possible Errors

AGI does not check that screen 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:

#define o3 ghost
ignore.objs(ghost);   [ this ghost can move through other objects
...
observe.objs(ghost);  [ now this ghost cannot move through other objects
