Tutorial: Flower Baricade

Level: Easy

Author: Ninja of Comp

I was trying to make a weapon that would shoot a seed of some sort and this seed would embed itself in its victim and after some time, it would germinate and explode its victim leaving a flower in its place.

Well, I haven’t finished that weapon yet but based on the research I did, I was able to make what I call a Flower Baricade. This is just a way to spawn a model, put dimentions on it so when a player tries to go trough it, he can’t, thus becoming a barricade. But also, after 10 seconds, it will explode and cause some damage to any player nearby.

Good too block doorways for a quick getaway.

Here we go! First create a file or incorporate the following code into you project file:

// ******************************************************

// * JMR: Flower Explode

// ******************************************************

void Flower_Explode(edict_t *flower)

{

flower->owner->client->flower = 0;

// Destroy the FLOWER in a big fireball.

G_Spawn_Explosion(TE_EXPLOSION2, flower->s.origin, flower->s.origin);

// Throw flower debris all over the place...

ThrowDebris(flower, "models/objects/debris2/tris.md2", 3.50, flower->s.origin);

ThrowDebris(flower, "models/objects/debris2/tris.md2", 2.50, flower->s.origin);

ThrowDebris(flower, "models/objects/debris2/tris.md2", 1.50, flower->s.origin);

ThrowDebris(flower, "models/objects/debris2/tris.md2", 4.50, flower->s.origin);

ThrowDebris(flower, "models/objects/debris2/tris.md2", 3.75, flower->s.origin);

ThrowDebris(flower, "models/objects/debris2/tris.md2", 2.30, flower->s.origin);

ThrowDebris(flower, "models/objects/debris2/tris.md2", 1.00, flower->s.origin);

// Assign any Radius Damage frags to the FLOWER's owner..

T_RadiusDamage(flower, flower->owner, 40, NULL, 400, MOD_SPLASH);

// Free the flower entity

G_FreeEdict(flower);

}

// ******************************************************

// * JMR: Create Flower

// ******************************************************

void Create_Flower (edict_t *ent)

{

if (ent->client->flower == 1) // if flower still exists, don't create again

{

return;

}

else // otherwise....

{

ent->client->flower = 1;

}

edict_t *flower; // define flower as an entity

vec3_t forward; // define foward as vector

flower=G_Spawn();

flower->s.modelindex = gi.modelindex ("models/objects/flower/tris.md2"); // The model

flower->owner = ent; // who's your dady?

flower->takedamage = DAMAGE_NO; // can't damage it

flower->movetype = MOVETYPE_TOSS; // throw this flower and it falls to ground

flower->solid = SOLID_BBOX; // the flower is solid

flower->nextthink = level.time + 5; // When to execute the think function (5 sec)

flower->think = Flower_Explode; // and this (Flower_Explode) is that function

VectorClear(flower->s.angles); // clear flower angles

AngleVectors(ent->client->v_angle, forward, NULL, NULL); // copy owners angles to flower

VectorMA(ent->s.origin, 100, forward, flower->s.origin); // Put the model in front of us

flower->s.origin[2] += 64; // a little higher please

// This should set the bounderies for our flower

VectorSet (flower->mins, -18, -18, -28); // a, b. c

VectorSet (flower->maxs, 18, 18, 18); // e, f, g

/*

o---------o

|\ |\ f

| \ | \ \

c | \ e- | \

| | o---------o <- maxs // might be wrong on a,b,e & f

| | | | // but i'm sure on c & g

mins -> o---|-----o | |

\ | -a \ | g

\ \ | \ |

b \| \|

o---------o

*/

gi.linkentity (flower);

}

Now go to g_local.h and add the the following lines at the end:

void Flower_Explode(edict_t *flower);

void Create_Flower (edict_t *ent);

Also go to g_cmds.c and add the following lines near the end of ClientCommands:

else if (Q_stricmp(cmd, "playerlist") == 0)

Cmd_PlayerList_f(ent);

// ******************************************************

// * JMR: Create Flower

// ******************************************************

else if (Q_stricmp (cmd, "flower") == 0)

Create_Flower (ent);

// *************************************************

else // anything that doesn't match a command will be a chat

Cmd_Say_f (ent, false, true);

Now you only have to bind that command to a key (example: bind f “flower”) and your set.

Explanation:

Everything should be easy to follow. Take note on that little box I made. It should give you an idea of how to set up bouderies for your models.

Final remarks:

You can do more than just a barricade. You can also create item models to lure out campers or other players. If you play around a little, you can even add a think function for proximity. That way, when the player gets close to the “item” he’ll receive some damage.

Have fun.
