Global Variable

[Jaguar_jwg]

Can I have a global variable that affects all the pawn scripts?
For example, suppose I wanted a pawn to move if BUTTON = “A”, and a next pawn to move if BUTTON = “B”, and so on.
This information is in a script that allows me to select the ‘buttons’ using the mouse. The pawns are activated individually depending on the button pressed.
Each pawn has its own script because their gravity is different.
Any information on this will be appreciated.

technially you can use the get attribute cmd
you can get attributes from other pawns
or set it in player.ini

[Jaguar_jwg]

I don’t understand.
How can the GetAttribute command help me?
Could you explain a bit please?

[WebsterX37]

why not use a trigger within the level, you can control the state of the trigger or maybe two triggers within your pawn scripts

GetEventState(char *Trigger );

Returns the trigger state

[Jay]

Yes. You can get and modify the variables from one script in another.
With variables i mean these (they are defined at the beginning of the script):

BUTTON [A] //for example

Lets say the pawn owning the variable Button is named Pawn1. Then another pawn Pawn2 can modify Pawn1's variable with 'calling' Pawn1's name and the variable:

Pawn1.BUTTON = "B";

Now Pawn1's BUTTON variable is B instead of A.

You could just use one of your pawns to store all the global variables and then you modify those when needed.
Attributes have the drawback that they only represent numbers and cannot be strings.

cool ... has this trick with the dot: Pawn.Variable been posted somewhere before or is it within the manual?

[Jaguar_jwg]

I think I am doing everything as you mentioned Jay, but nothing is happening. It's not working.

In the script for Pawn3 I have the variable: ACTION = "test";
I also have: ShowText(3, "", "", ""#ACTION#"", FONT, "", 240, 60, "center", 255);
The text "test" shows up on the screen.

In the script for Pawn1 I have:
if(self.lbutton_pressed)
{
Pawn3.ACTION = "Pass";
}
The text does not change. Am I missing something. If I am could you write the script for me using the above outline? Thanks

[Jay]

Do you draw the text every frame (ShowText holds the text i think if you don't change it)? Does it give you any errors? Try Console(true) to check if you have any errors.

If not, could you post both scripts please?

[Jaguar_jwg]

I get an error: Field Pawn3 not found
Pawn 3 does exist though.

Here is the script for Pawn3:
{

FONT [10]

Spawn[()
{
Console(true);
HideFromRadar(true);
Gravity(false);
LowLevel("SelectEntityByMouse");
}]

SelectEntityByMouse[()
{
SW = GetScreenWidth(); // ScreenWidth
SH = GetScreenHeight(); // ScreenHeight
ACTION = "test";
NAME = MouseSelect(true, false, 255,255,255,
255,255,255);

if(NAME = "")
{
ShowText(1, "", "", "Nothing Selected", FONT, "",
SW/(2), 100, "center", 255);
}
else
{
ShowText(1, "", "", "This is "#NAME#".",FONT,
"", SW/(2), 150, "center", 255);
}

ShowText(2, "Object1", "", "Box", FONT, "", 0, -30,
"center", 255);
ShowText(3, "", "", ""#ACTION#"", FONT, "", SW/(2),
60, "center", 255);

if((self.lbutton_pressed) and (NAME = " Object1"))
{
for AA = 1 to 32
{
RemoveText(2);
}
ShowText(2, " Object1", "", "Box", FONT, "", 0, -30, "center",
255);

PlayAnimation("", true, "");
RestartOrder();
}
}]

}

Here is the Pawn1 script:

next time put it in code markers pliz,easier to read.

[Jay]

are you sure the szEntityName of the Pawn whose variable you want to modify is "Pawn3"? It looks for the szEntityName of the Pawns.

Also, you didn't define the variable ACTION at the top of the script. If you define a variable in an order it might work that you can use the variable in the script itself, but after the order is finished the variable will get deletetd.

You must define it at the top of the script with

ACTION [test]

then it should work. Variables that are declared like this always count for the whole script.

[Jaguar_jwg]

Thanks Jay, I try that out.
Sorry Zany..., I thought about doing that but forgot.

[Jaguar_jwg]

The error has moved, but nothing happens. Do I have to change any part of the scripts in order for the variable to show up as "pass" on the screen?

[Markman]

It looks like you are overwriting the variable "ACTION" continiously in the first script as the order is looping.
So when you changed it in the second script it is instantaneously changed back to the first value.

You have to define and init the variable in the HEADER. You can also init it in a order that is before the Mainloop-order.
