hey there, i´m working on a space shooter as my first game and i would like to know how to make an enemy shoot every x seconds. i tried to set an alarm in the enemy´s step event but it wont run it.

You should post your code as that is helpful (often necessary) to answer the question. But most likely, you are resetting the alarm before it finishes. For example, if you are doing this:

Code:
``````///step event
alarm[0] = 60;``````
Then every single step the alarm gets set to 60, counts down to 59, and is reset again. There are many solutions to this problem, but the simplest one that uses the built in alarms is this:

Code:
``````if (alarm[0] == -1) {
alarm[0] = 60;
}``````
This will only set the alarm if the alarm is equal to -1 which is what alarms are in GM when they are off.

Other options (which might be helpful just in general to understanding how this type of problem is dealt with) are:

If your AI is really simple, just set the alarm in the Create event and in the Alarm event itself so it cycles infinitely.
