I was wondering if it were possible to change the projectile type for a weapon.

For instance, is it possible to make a rocket launcher fire a Sandman ball instead?

SDKHooks will be available in the plugin I'm working on, so anything involving SDKHooks is OK.

replace entity?
when tf_projectile_rocket creates
get position and velocity
create tf_projectile_ball
set owner and velocity
and... done?

this is how I would try

Unfortunately, it's implied in this thread that simply spawning a new entity won't make it work like the actual projectile would.

but how when game itself can do so? D:
afaik from sdk, weapon creates projectile entity with params, etc

Just curiously, in your first example, would you want the rocket-turned-sandman-balls to stun the player upon hit, or explode like a normal rocket with with the ball model instead?

Stun the player. I already know how to change the actual model used (SetEntityModel).

Anyway, using an OnEntityCreated with a timer (because the properties aren't assigned for another game frame) doesn't appear to work. The code I tried is attached.

I added in the TeleportEntity when I saw weird VPhysics errors regarding the position of the tf_projectile_stun_ball entity in the server log. However, the baseball is never actually seen.

You need to hook Spawn in OnEntityCreated, then do your work in that callback.
Not that that would actually help with the fact the balls aren't appearing.

SpawnPost.
I tryed it, but results are same - nothing. no balls, no rockets, no errors. sad panda :c

EDIT:
Oh! Maybe you need to set model?

I looked a bit inside the function that spawns the stun ball, and I saw that it calls these two virtual functions: CTFWeaponBaseGrenadeProj::InitGrenade() and CTFWeaponBaseGrenadeProj::SetLauncher()

It also sets a variable (pseudo code)

 *(float *)(pGrenProjectile + 1232) = tf_scout_stunball_base_speed.GetFloat();

Maybe if you call these two virtual functions I mentioned with sdktools, and then use SetEntDataFloat() to set the value of the variable..

I don't know what values that needs to be passed into these functions, or if the offset of the variable is the same on all platforms (I got it from the Mac binary). Maybe if someone look into this into this with IDA, you may be able to spawn a stun ball in SM
