Objects and Datablocks

by Demolishun · in Torque Game Engine · 09/16/2004 (9:50 pm) · 1 replies

Here is some code I have been experimenting with:

// Start Code

//
// Test Datablock
//
datablock SimDataBlock(vehicleData)
{
type = "generic";
};

datablock SimDataBlock(carData : vehicleData)
{
type = "car";
};

datablock SimDataBlock(truckData : vehicleData)
{
type = "truck";
};

new SimObject(vehicleObject)
{
datablock = "vehicleData";
};

new SimObject(carObject : vehicleObject)
{
datablock = "carData";
};

new SimObject(truckObject : vehicleObject)
{
datablock = "truckData";
};

function SimObject::ShowType(%this)
{
echo(%this);
echo(%this.type);
echo(type);
}

vehicleObject.ShowType();
carObject.ShowType();
truckObject.ShowType();

// End Code

The output of this code is as follows:
vehicleObject

type
carObject

type
truckObject

type

I ran the tree() function and noticed that instead of including the datablocks in the objects it added a variable called datablock that was set to the text corresponding to the name of the datablock provided. Is that how I am supposed to access the data? For example:
%tempblock = carObject.datablock;
echo(%tempblock.type);

Thanks,

    Frank,

    You could do that, or alternately, if you have the ID (handle) to an object, you can use the getDatablock() console method: 

    %obj.getDatablock();

    All objects derived from/initialized with a datablock (which is all GameBase children) will have a datablock field in them.

    BTW, I see in your code that you are using some 'reserved' names as your datablock names:

    datablock SimDataBlock(carData : vehicleData)
{
type = "car";
};

    In the above code, vehicleData happens to be a named datablock so it's not adviseable to use this name in your actual code.

    You should probably take a look at the on-line docs: here

    also, there is a complete list of datablocks here

    I hope this helps. Also, I'll be releasing a newer version of EGTGE (see link below) soon (means watch for release notice) so you might want to grab that too.
