How to change actor's scale on the fly?

[ramon.dexter]

So, BlueShadow helped me with setting damage on the fly. I tried using the same method for setting scale on the fly, but gzdoom returns error "call to unknown function getScale()", but, the function IS defined in the class. So I clearly don't understand this error. How should I do that so gzdoom works?
I have to note that the 'getPwrupDamage()' is recognized and works, so I don't understand why the 'getScale()' is ignored.

Here is the projectile code:

Code: Select all

class shadowGunPoweredupProjectile : FastProjectile
{
	int getScale()
	{
		int scl = 0.8;
		if(target && target.CountInv("pwrLevel") == 8)
		{
			scl = 0.8;
		}
		if(target && target.CountInv("pwrLevel") == 7)
		{
			scl = 0.8;
		}
		if(target && target.CountInv("pwrLevel") == 6)
		{
			scl = 0.6;
		}
		if(target && target.CountInv("pwrLevel") == 5)
		{
			scl = 0.6;
		}
		if(target && target.CountInv("pwrLevel") == 4)
		{
			scl = 0.4;
		}
		if(target && target.CountInv("pwrLevel") == 3)
		{
			scl = 0.4;
		}
		if(target && target.CountInv("pwrLevel") == 2)
		{
			scl = 0.2;
		}
		if(target && target.CountInv("pwrLevel") == 1)
		{
			scl = 0.2;
		}
		return scl;
	}
	
	int getPwrupDamage()
	{
		int dmg = 16; //base damage, when player is on level 0 & level 1
		if(target && target.CountInv("pwrLevel") == 8)
		{
			dmg = 72;
		}
		else if(target && target.CountInv("pwrLevel") == 7)
		{
			dmg = 64;
		}
		else if(target && target.CountInv("pwrLevel") == 6)
		{
			dmg = 56;
		}
		else if(target && target.CountInv("pwrLevel") == 5)
		{
			dmg = 48;
		}
		else if(target && target.CountInv("pwrLevel") == 4)
		{
			dmg = 40;
		}
		else if(target && target.CountInv("pwrLevel") == 3)
		{
			dmg = 32;
		}
		else if(target && target.CountInv("pwrLevel") == 2)
		{
			dmg = 24;
		}
		else if(target && target.CountInv("pwrLevel") == 1)
		{
			dmg = 16;
		}
		return dmg;
	}

DamageFunction is a special case. You'll want to change the actor's scale somewhere else, maybe in a PostBeginPlay() override.

You can change the actor's scale anytime, e.g.:

Code: Select all

scale=(-1.1,1.1); 

which would make the thing 10% bigger on each dimension and flipped horizontally.

Or you can use the scale as a variable:

Code: Select all

tracer.damagemobj(self,target,100*scale.y,... //inflict damage multiplied by Y scale  

Code: Select all

scale*=0.9; //reduce scale to 90% of whatever it was before

Oh, that's cool Many thanks!
