AGIWiki/shake.screen

The shake.screen command shakes the screen a specified number of times.

shake.screen(shakeCount);

The screen is shaken shakeCount times. The screen is "shaken" by moving the entire screen image around on the monitor to give a violent tremor effect.

Note: although shaking the screen 100 or more times is not recommended (because the screen will shake for a long time), it should be noted that the shake.screen command is altered if you are using AGIPAL so that any value between 100 and 109 changes the game's palette instead of shaking the screen.

Parameters

shakeCount: a number, 0-255, specifying how many times to shake the screen

Possible errors

Some interpreters, such as NAGI, do not support the shake.screen command and will do nothing if the command is issue. It is safe to issue the command on these interpreters, but it will be ignored.
Specifying a value of 0 for shakeCount appears to make the screen shake forever.

Examples

The following code will shake the screen five times whenever the player enters this room:

 #include "defines.txt"

 if (new_room)
 {
     load.pic(room_no);
     draw.pic(room_no);
     discard.pic(room_no);

     draw(ego);
     show.pic();

     shake.screen(5);
 }

</syntax>
