SendMessageExRadius?
2002-02-10, 1:36 AM #1
What does this MotS library function do? It's used in all the force power COGs as such:
Code: 
        // Send a "force disturbance"...
         if(!IsMulti())
            SendMessageExRadius(GetThingPos(player), cost, 0x4, splash, 31, 0, 0, 0);


Apparently the parameters are:

vector center
flex radius
int (unknown purpose)
message (unknown purpose)
int/flex param0
int/flex param1
int/flex param2
int/flex param3

I didn't notice any effect this line had in SP. The message (splash) sent obviously isn't being sent to a cog, because there's no cog reference. So what could it be sending it to?

maybe it sends a message to any things within a given radius.. dunno.

But then why would the developers want a "Force disturbance" to make things within a radius splash as though they entered water? That doesn't make sense.

Maybe splash is a variable? [http://forums.massassi.net/html/confused.gif]

No, it's not declared in the symbols section.

I was hoping to use this line to send a message to players within a thing's radius... I guess I'll have to calculate eveything manually.

What's the algebraic equation for a sphere again?
(x-a)^2+(y-b)^2+(z-c)^2 = R^2 I think...

As it's used there, SendMessageExRadius() will call the splash message in the cog of any actor within the radius. I guess the syntax is:
Code: 
SendMessageExRadius(pos, radius, mask_flags, message, p0, p1, p2, p3);

Open up actor_rc.cog and put in a splash message containing a print(). Then play the New Republic base mission. When you use force jump, the cog of every actor within 20 JKUs will print a string.

Strange that LEC didn't use any "force disturbance" code in their actor cogs.

Wow, if that's the case, it's exactly what I was looking for (provided it can message players in MP as well). I'll give it a shot. Thanks SaberMaster [http://forums.massassi.net/html/smile.gif]

I think they wanted to make waters jump small, like heavy things walking beside a water pool, just to make things look cool, but ended up as nothing.

But then again, water surfaces usually don't have a cog attached, so what the nuts?

Maybe they wanted to use the splash message because it was unused in actor cogs.

I got it! I tested the cog and these are my final conclusions.

Code: 
void SendMessageExRadius(vector center, flex radius, int thing_type_mask, message target_msg, flex param0, flex param1, flex param2, flex param3)


The message calls 'target_msg' in any thing's class cog within 'radius' JKUs from 'center'. The types of things that will be messaged are determined by setting 'thing_type_mask' flags.

This is an extremely useful function. It can be used to make very sophisticated cog-based AI: it can be used to notify actors of the player's actions. For instance, you could have Rodians run away if the player pulls out the conc.
