Hi I'm trying to spawn bullets from a gun and can easily do that but I am a bit at a loss on how to expand my functionality.

I am trying to create a family to hold all my various bullets with a family instance variable of bullet_type so I can uniquely identify each bullet and switch types. My end goal is to use a global variable compare to select the correct bullet to spawn depending on powerups. The spawn object action asks me to specify a specific object though. Is there anyway to do something like:

spawn family object where instance variable = power_bullet

or something?

Any suggestions about how to go about this?

No, this is not possible. When you spawn a family, a random member of the family will be created.

You should use "Create by name" action. For example:

Create object by name "Bullet"&BulletType

After that if you need to change any bullet property, add a sub-event "System pick last created BulletFamily" and there you can set bullet angle, speed etc.

Thank you! Just incase anyone in the future stumbles upon this here is a visual representation:

Just toggle the bullet global variable to the bullet object's name you want switched to.
