Something random inside a scene?

[Hipshot]

Is it possible to have something like "TNT1 A 0 A_StartSound("alert", CHAN_VOICE);" happen by random in a scene. I understand that I can just do a jump randomly to another scene, but that requires me to do another scene and jump back, if I keep doing that I end up with tons of small scenes everywhere.

Yes.

Code: Select all

TNT1 A 0
{
	if (random() < 32)
	{
		A_StartSound("alert", CHAN_VOICE);
	}
}

Nice, is the number 32, 32 out of 255 here where 255 is 100%/1.0?

[Blue Shadow]

Yes. random(), without passing any args to it, returns a value that ranges from 0 to 255.

Ok, I see.

I noted that this can't be "outside" a spritename (not sure what it's called really), but it has to be inside like in your example TNT1?

So this wont work, throws me an error:

TNT1 A 0 A_StartSound("alert", CHAN_VOICE); GUAA A 3 A_FaceTarget; { if (random() < 32) { GUAA F 4 Bright; } } GUAA B 3 ThrustThing(angle*256/360+192, 3, 0, 0); GUAA ABCD 4 A_Wander();

Because it assumes that the entire section there is suppose to be inside the a_facetarget sprite group?

[Blue Shadow]

No, it can't. The block of code in-between the curly braces (the outer ones, that is) is basically a function, and you can't have more than one function attached to a single state. So what you do is execute A_FaceTarget from within the anonymous function, like this:

Code: Select all

GUAA A 3
{
	A_FaceTarget();

	if (random() < 32)
	{
		// ...
	}
}

Ok, good to know. Had been even goodlier otherwise =)
