How to set projectile damage on the fly?

[ramon.dexter]

So, here is my situation:
I got a inventory item "pwrLevel" that indicates player's "power" - health&damage.

How do I modify projectile's damage on the fly? I dont want to make a long A_JumpIfInventory list, so I want to use zscript to modify the projectile's damage.
When I used this:

Code: Select all

TNT1 A 0
			{
				if(countinv("pwrlevel") == 1)
				{
					wrstCannonProjectile.damage = 4;					
				}
			
			}

The parser returned following error:
"Unable to access 'wrstCannonProjectile.Damage' in a static context"

So, how do I modify the projectile's damage/damagefunction?

edit: Also, I dont want to use powerup, because it modifies damage of all weapons. I need to raise damage of one weapon.

Create a function which would calculate and return the damage, and pass it to DamageFunction:

Code: Select all

class BlahProjectile : Actor
{
    Default
    {
        DamageFunction GetDamage();
    }

    int GetDamage ()
    {
        int dmg = 30;

        // The target of a projectile is its shooter.
        if (target && target.CountInv("Something"))
        {
            // Multiply the base damage by 2 if the shooter has the item.
            dmg *= 2;
        }

        return dmg;
    }
}

Thanks, works as expected

edit: Need to thank you again, this time I tested it and it it really a gem, thank you a lot!

One more thing to ask: When "target" is projectile's shooter, how is the ... umm ... target, point the projectile heads to, called?
