Cluster Grenade
1/27/1999
Well this is always a fun grenade to make and have in any game. They are very simple to make too!
This will show you how vectors work and show that angles are all in radians. Here is a pic of the grenade
in action and what to expect when you are done. This grenade will shoot out 4 grenades right when it explodes(
okay actually just a little bit before but with lag over the internet you won't be able to tell the difference).
Ok first open up mine.cs and put at the bottom this code
MineData Cluster
{
mass = 0.35;
drag = 1.0;
density = 2.0;
elasticity = 0.15;
friction = 1.0;
className = "Clustergrenade";
description = "Handgrenade";
shapeFile = "grenade";
shadowDetailMask = 4;
explosionId = debrisExpSmall;
explosionRadius = 5.0;
damageValue = 0.5;
damageType = $ShrapnelDamageType;
kickBackStrength = 60;
triggerRadius = 0.5;
maxDamage = 0.9;
};
function Cluster::onAdd(%this)
{
%data = GameBase::getDataName(%this);
schedule("Mine::Detonate(" @ %this @ ");",0.85,%this);
}
This is the data for the cluster grenade. Now that we have this defined modify the hand grenade so it looks like
this.
MineData Handgrenade
{
mass = 0.4;//JR a little heavier(yes I know its not what it should be that weighs too much)
drag = 1.0;
density = 2.0;
elasticity = 0.25;//JR increased it for the hell of it
friction = 1.0;
className = "Handgrenade";
description = "Handgrenade";
shapeFile = "grenade";
shadowDetailMask = 4;
explosionId = debrisExpMedium;//JR different explosion other one too big for this
explosionRadius = 1.0;//JR shrunk down the radius
damageValue = 0.5;
damageType = $ShrapnelDamageType;
kickBackStrength = 10;//JR not as much kick back
triggerRadius = 0.5;
maxDamage = 0.5;//JR less damage
};
Okay this just sets up the hand grenade so it does less damage and has a different explosion and some misc
other things well here is the code that does it all now.
function ThrowCluster(%this)
{
%vect[0]= 0.7853981633974;
%vect[1]=1.570796326795;
%vect[2]=- 3.1415926536;
GameBase::setRotation (%this,%vect[0] @ " " @ %vect[1] @ " " @ %vect[2]);
%obj = newObject("","Mine","Cluster");
addToSet("MissionCleanup", %obj);
GameBase::throw(%obj,%this,0.6,false);
%vect[0]= 0.7853981633974;
%vect[1]=1.570796326795;
%vect[2]=- 1.570796326795;
GameBase::setRotation (%this,%vect[0] @ " " @ %vect[1] @ " " @ %vect[2]);
%obj = newObject("","Mine","Cluster");
addToSet("MissionCleanup", %obj);
GameBase::throw(%obj,%this,0.6,false);
%vect[0]= 0.7853981633974;
%vect[1]=1.570796326795;
%vect[2]= 0;
GameBase::setRotation (%this,%vect[0] @ " " @ %vect[1] @ " " @%vect[2]);
%obj = newObject("","Mine","Cluster");
addToSet("MissionCleanup", %obj);
GameBase::throw(%obj,%this,0.6,false);
%vect[0]= 0.7853981633974;
%vect[1]=1.570796326795;
%vect[2]= 1.570796326795;
GameBase::setRotation (%this,%vect[0] @ " " @ %vect[1] @ " " @ %vect[2]);
%obj = newObject("","Mine","Cluster");
addToSet("MissionCleanup", %obj);
GameBase::throw(%obj,%this,0.6,false);
}
What that code does is throw 4 cluster grenades and rotating the main grenade every time before
it so it gets thrown the right direction. As you can see vector our actually a string with 3 floats and
spaces inbetween. Set rotation sets up the right angles for each grenade. Now one more line of code needs to
be added for it to work.
function Handgrenade::onAdd(%this)
{
%data = GameBase::getDataName(%this);
schedule("ThrowCluster(" @ %this @ ");",1.99,%this);//JR This throws out all the grenades
schedule("Mine::Detonate(" @ %this @ ");",2.0,%this);
}
Okay all that does is sets it up so it will throw the grenades a 1/100 of a second before the
grenade blows up first off not too many people get a 100+ fps so no will likely see them coming out
before the explosion. You say why not add them in Mine::Detonate because mines also use it. Which to tell
you I hope to have a tutorial tomorrow for team mines. Well that wraps it up pack and go try it out! Email
me any tutorials you have written.
