Accessing custom property dynamically

[malon3]

How do I access the "AmmoUsage" property from the projectile?

The name of the gun is "CompanionZombieManGun" and there will be many more gun types that inherit from BaseGun, so how can I do this dynamically?

Code: Select all

class BaseGun : Weapon
{
  int AmmoUsage;
  property AmmoUsage : AmmoUsage;
  Default
  {
    Weapon.AmmoUse1 0;
    BaseGun.AmmoUsage 0;
  }
  States
  {
    Fire:
      TNT1 A 0 A_FireProjectile("myProjectile");
  }
}

class CompanionZombieManGun: BaseGun
{
  Default
  {
    Weapon.AmmoUse1 1;
    BaseGun.AmmoUsage 2;
  }
}

class myProjectile : Actor
{
  TNT1 A 0
  {
    Death:
      console.printf(target.player.readyweapon.AmmoUse1..""); // no error when compiling this line
      console.printf(target.player.readyweapon.AmmoUsage..""); // complains about AmmoUsage Unknown identifier
  }
}

You'd have to cast your weapon to BaseWeapon - but it's ot that easy because it will fail if you switch weapons before the projectile hits something.
Your code may randomly abort both on target.player and target.player.readyweapon. You should access neither in the projectile.

Your only safe way would be to copy the needed info from the weapon to the projectile when being spawned.

Thank you, I had already prepared for the weapon changing before impact. I saved the state before the shot and after the shot.

My mistake was thinking that casting to the parent class would affect values set by the child class.

Thank you Graf, you've answered several of my dumb questions.
