Creating a random object upon destroying another object?

[ACGOS]

I want to launch a random powerup whenever I destroy a certain object instead of getting the same powerup every time. However, I don't know how to randomize the powerups so the outcome is different each time. How do I do this?

when you create the a certain object set a value to it. and use the random range. This way you can set an alt value to a random value, and then check for a specific, or a value in a range when it is destroyed, and reward the player on certain values, and not reward on others, or just ahve other rewards on those values.

I have random dorp for my enemy example:
start of frame: set alt value loot1 to RRandom(0, 4 )

and when they die:
health <= 0 start lopp for each certain object named "dead"

On each on of "ceratain object", loop named dead
and value loot1 lower or equal to 1 create object laser gun

On each on of "ceratain object", loop named dead
and value loot1 greater than 1 create object pipe

On each on of "ceratain object", loop named dead
Destroy
