Ammo count and such?

#1 Check in crossbow.cs the definition of the datablock

datablock ShapeBaseImageData(CrossbowImage)

// No ammo dry fire
stateName[6] = "DryFire";
stateTimeoutValue[6] = 1.0;
stateTransitionOnTimeout[6] = "NoAmmo";
stateSound[6] = CrossbowFireEmptySound;

#2 Yeah, saw all that. Where are these states changed? Again, looking through the script files I see nothing that references weapon states. In fact, this is what started my quest. I wanted to set the no ammo flag when my player entered a trigger.

So, for example, when/where is the stateTransitionONTimout[6] state set? And what the heck are these variables anyway? Can I use them as: crossbow.statTransitionOnTimeout[6] = um, what? or crossbow."NoAmmo" = .... which makes even less sense. What are these anyway? An array?

So many questions.

#3 All the weapon state stuff is implemented in C++, specifically, in game/shapeImage.cc, if memory serves.

Don't edit datablocks on the fly; they aren't set up to be updated properly and the results will be unpredictable.

#4 Yes, ShapeBase has the definitions for the various weapon state arrays. The question is, where are these manipulated? For example, when I run out of ammo, I'm expecting some code somewhere to say:

ShapeBase.weaponstate[x] = something

-OR-

ShapeBase.weaponstate=something[x]

My pseudocode is not exactly precise, but the basic concept is where are these weaponstates actually changed as the game progresses?

#5 In the weapon files themselves right (crossbow.cs?)

Like the crossbow "onFire" funtion has something like

%obj.decInventory(%this.ammo,1);

Where the ammo is decreased by one.

#6 Which takes us to this in inventory.cs. Of interest here is the setinventory call

function ShapeBase::decInventory(%this,%data,%amount)
{
// Decrement the inventory by the given amount. The return value
// is the amount actually removed.
%total = %this.inv[%data.getName()];
if (%total > 0) {
if (%total < %amount)
%amount = %total;
%this.setInventory(%data,%total - %amount);
return %amount;
}
return 0;

--------------------- Which then takes us to:

function ShapeBase::setInventory(%this,%data,%value)
{
// Set the inventory amount for this datablock and invoke
// inventory callbacks. All changes to inventory go through this
// single method.

// Impose inventory limits
if (%value < 0)
%value = 0;
else {
%max = %this.maxInventory(%data);
if (%value > %max)
%value = %max;
}

// Set the value and invoke object callbacks
%name = %data.getName();
if (%this.inv[%name] != %value)
{
%this.inv[%name] = %value;
%data.onInventory(%this,%value);
%this.getDataBlock().onInventory(%data,%value);
}
return %value;
}

This looks like a dead end to me when it comes to weapon states. (This is as far as I got when I decided to post my question.)

I'm expecting something somewhere to refer to the ShapeBaseImageData datablock weapon state arrays. So far, it hasn't shown up.

Quote:All the weapon state stuff is implemented in C++, specifically, in game/shapeImage.cc, if memory serves.

#8 I was looking at this thread because I wanted to show a label on the screen that tells the player what is the ammo count. It works great until the bots starts shooting, the counter gets all crazy.
I think is because I am calling a function that updates the label inside the decInventory inside the inventory.cs file that is on the server side of the code.

Now my question is this one: How do I know which one is the client that the ammo count is getting updated for? And how do I update a labelTextCtrl in the HUD only for this client?

Thanks

#9 Juan, you should take a look at how commandToServer/Client works, and how storing of local variables work. To me it sounds like you're using globals.

In onFire for your weapon, do a commandToClient to %obj.client (or somesuch) and send the variable for how much ammo is left.
