+forward

A while back I experimented with using the +forward console command to impose player behavior. This was ok, but obviously not the best solution.

Is there an equivalent Decorate Actor property to the +forward console command?

Thanks!

After playing with this for a bit, I'm using A_Recoil with a negative value - which does exactly what I want:

Code: Select all

        Spawn:
            POSS A 1 A_PlaySound ("fly", 1, 1.0, 1)
			   POSS A 1 A_Recoil(-4)
			   POSS A 1 A_ChangeVelocity (0, 0, 1, CVF_RELATIVE) 
            Loop

As you mentioned, it doesn't affect the Z-axis at all. I can turn left and right, but not up or down. Using A_ChangeVelocity simply shoves the player up or down, ignoring the mouse.

Can I invoke the +forward console command via decorate?

No.

Finally figured it out with the help TheMisterCat on the Zandronum IRC. I'm not a math person...

This is my solution:

Code: Select all

//     Actor properties to limit player control:
Player.ForwardMove 0.00, 0.00
Player.SideMove 0.00, 0.00

Code: Select all

States
{
     POSS A 1 A_PlaySound ("jetengine", 1, 1.0, 1)                  //  Play engine/flight sound.
     POSS A 1 SetPlayerProperty(0, 1, 3)                            //  Set fly property.
     POSS A 1 A_Recoil(-4)                                          //  Set player movement.
     POSS A 1 A_ChangeVelocity(0, 0, -sin(pitch)*5, CVF_RELATIVE)   //  Affect the z-height based on pitch.
     LOOP
}

And VOYLAY! YOUR OWN JET TO PILOT!

Now that you're using A_ChangeVelocity, you don't even need A_Recoil any more.

I tried that first and couldn't get it to move straight forward - it would always slide to the side.

Works fine for me. (*Plug plug*)

[Galaxy_Stranger]

You're absolutely right!

Code: Select all

A_ChangeVelocity (-Cos(Pitch) * -10, 0, -Sin(Pitch) * 10, 1)
