zdoom how to make monster fire two projectile at once ?

[Mewdoom]

Hello everyone,

I wonder how to make a monster that will fire two projectile at once ? Like the Mancubus, and how to set the proper distance between the shot of projectiles to adjust it properly with the position of the weapon that shoot that projectiles ?

The simplest way to do that is to fire the first projectile in a state with a zero tic length, and then fire the second projectile. This will result in both projectiles to be fired at the same time (instructions are run immediately when the actor enters the new state).

I wonder too how to make a projectible shootable and make him follow his target like the skeletton missile ?

Then fire it using A_Tracer.

Disregard this part, please. Any generic missile shooting function in DECORATE can handle this

A_Tracer is not a missile firing function that a monster could use to fire the missile, but it's a missile movement function that's needed to be called in the missile's own flight frames to make the homing effect work.
