Basic Health Demo

1. In default.bind.cs, add this line:

//------------------------------------------------------------------------------
// Item manipulation
//------------------------------------------------------------------------------

moveMap.bindCmd(keyboard, "h", "commandToServer('use',\"HealthKit\");", "");
moveMap.bindCmd(keyboard, "2", "commandToServer('use',\"Crossbow\");", "");

2. In demo/client/config.cs, append this line:
moveMap.bindCmd(keyboard, "h", "commandToServer('use',\"HealthKit\");", "");

3. Copy from example folder of your torque sdk and add health.cs to demo/server/scripts.
health.cs should contains

//-----------------------------------------------------------------------------

// Inventory items. These objects rely on the item & inventory support
// system defined in item.cs and inventory.cs

//-----------------------------------------------------------------------------
// Health kits can be added to your inventory and used to heal up.
//-----------------------------------------------------------------------------

datablock ItemData(HealthKit)
{
// Mission editor category, this datablock will show up in the
// specified category under the "shapes" root category.
category = "Health";

// Basic Item properties
shapeFile = "~/data/shapes/items/healthKit.dts";
mass = 1;
friction = 1;
elasticity = 0.3;

// Dynamic properties defined by the scripts
pickupName = "a health kit";
repairAmount = 50;
};

//this function will activate when the player pressed 'h' to use his healthkit.
function HealthKit::onUse(%this,%user)
{
// Apply some health to whoever uses it, the health kit is only
// used if the user is currently damaged.
if (%user.getDamageLevel() != 0) {
%user.decInventory(%this,1);
%user.applyRepair(%this.repairAmount);
if (%user.client)
messageClient(%user.client, 'MsgHealthKitUsed', '\c2Health Kit Applied');
}
}


//-----------------------------------------------------------------------------
// Health Patchs cannot be picked up and are not meant to be added to
// inventory. Health is applied automatically when an objects collides
// with a patch.
//-----------------------------------------------------------------------------

datablock ItemData(HealthPatch)
{
// Mission editor category, this datablock will show up in the
// specified category under the "shapes" root category.
category = "Health";

// Basic Item properties
shapeFile = "~/data/shapes/items/healthPatch.dts";
mass = 1;
friction = 1;
elasticity = 0.3;

// Dynamic properties defined by the scripts
repairAmount = 20;
maxInventory = 0; // No pickup or throw
};

function HealthPatch::onCollision(%this,%obj,%col)
{
// Apply health to colliding object if it needs it.
// Works for all shapebase objects.
if (%col.getDamageLevel() != 0 && %col.getState() !$= "Dead" ) {
%col.applyRepair(%this.repairAmount);
%obj.respawn();
if (%col.client)
messageClient(%col.client, 'MsgHealthPatchUsed', '\c2Health Patch Applied');
}
}

4. Create a new items folder under data/shapes, and copy from example folder of your torque sdk and add healthKit.dts, healthKit.jpg, and healthPatch.dts.

5. Check demo/server/demo/player.cs has the following line:
// Allowable Inventory Items
maxInv[BulletAmmo] = 20;
maxInv[HealthKit] = 1;


6. Add the following line to fps/server/scripts/game.cs
// Load up basic datablocks, objects etc.
exec("./audioProfiles.cs");
exec("./camera.cs");
exec("./markers.cs");
exec("./triggers.cs");
exec("./inventory.cs");
exec("./shapeBase.cs");
exec("./health.cs");
exec("./staticShape.cs");

7. Go to your fps game, press F11 to acccess the mission editor and then F4 to access the world editor creater. You will find 4 folders on your right, namely, interiors, shapes, static shapes and mission objects. Click on shapes -> Health. Then choose either healthkit or health patch to add it into the mission. Remember to click on the menu bar File -> Save Mission As if you want the change to persist after you exit from the mission.

Thats all. Hope it is useful to newbies.
