Hullo, geeks and gamers.

I just got the Project Blue mod, and I've been toying around with all kinds of cool things.

When I read about the "movable lights", I was totally stoked because I realized how easy that makes scripting a flashlight or headlamp. Yay!

Here's my script -- it works beautifully -- you just need to apply it to a dynamic light in the scene, and place the light close to the player's start position.

+ Code Snippet


; AI script

desc    = Headlamp (by MandoAndy)

; This script mimics a headlamp that can be turned off and on with the middle mouse button.
; Assign this script to a dynamic light, and place the light close to the player's starting position in the map.

; The light will be off by default.

:state=0:mlighton,lightoff
:state=0:mlightrange=0
:state=0:mlightfollowplr
:state=0,mouseclick=4:state=2,sound=audiobank\sfx\light_click.wav

:state=1:mlighttype=1
:state=1:mlightid=827
:state=1:mlighton
:state=1:mlightfollowplr
:state=1:mlightrange=275
:state=1:mlightred=255
:state=1:mlightgreen=255
:state=1:mlightblue=150
:state=1,mouseclick=4:state=4,sound=audiobank\sfx\light_click.wav

; These timers are designed to keep the light from turning off and on too rapidly while the player clicks the mouse button.

:state=2:timerstart,state=3
:state=3,timergreater=200:state=1

:state=4:timerstart,state=5
:state=5,timergreater=200:state=0

; Never again shall we fear the dark!

So that's all pretty cool and nifty. I have a problem though that I CANNOT solve, so I need the help of the super awesome smart people here.

There's a trap in one of my levels, and if the player falls into the hole, s/he dies. (original, no?) My problem is that when the player respawns, the light never follows the player back to the respawn position!

I realize that I could probably solve this problem by repositioning the x, y, and z coordinates of the light when the player's health is less than 1 -- but this might not solve all problems, (multiple respawn points, etc.) and it just feels like there should be a better answer.

Any thoughts?

Wow, I should play around with that movable light feature. Haven't had a chance.

To be honest, I don't think that that is your best option unfortunately. I think the only way around it is to have 1 life. That's how most modern games do it nowadays, if you die, you respawn from an earlier save (autosave or not) and not in the same area.

However in the future when Fenix Mod merges with PB it should have the Horror Mod flashlight, which is really cool.

Thanks, Shadowtroid -- yeah, I agree. Even if I decide to go with only 1 life (which is probably how I will end up designing it) it still frustrates me that I can't quite figure this one out.

I'm not an expert at coding. Can you state the player's position as a variable? For instance, would this script (hypothetically) work? Or, is there a way to make the script's concept work?

+ Code Snippet


:always:DimVar=x_position,DimVar=y_position,DimVar=z_position

:always:setvar=x_position %PlrPosX,setvar=y_position %PlrPosy,setvar=z_position %PlrPosZ

:always:mlightx=%x_position
:always:mlighty=%y_position
:always:mlightz=%z_position

Is there an easy way to keep track of and call the player's current X, Y, and Z coordinates? It should be easy to do... I feel like I should be able to state the coordinates as a variable somehow, but I'm not sure how to do it. (I just used the term "plrposx, plrposy, and plrposz" for demonstrative purposes - I have no idea if that would actually work)

Thanks for your insight, though

I can't way to see that horror mod flashlight!

Already did this with the release of my Modern Warfare pack a while ago

.

Here's my script if you interested in comparing.

;Artificial Intelligence Script

;Header

desc = Flashlight Script

;Script which activates Flashlight when "F" is pressed
;Adjust the range and light colour in the code in state 0.
;Script by Marc Steene from the Modern Warfare Script Pack

;Triggers

:state=0:dimvar=flashlight,setvar=flashlight 0,etimerstart,mlightrange=200,mlighttype=1,mlightid=250,mlightred=228,mlightgreen=220,mlightblue=218,state=1
:state=1,scancodekeypressed=33,varequal=flashlight 0,etimergreater=500:setvar=flashlight 1,sound=audiobank\music\flashlight off.wav,etimerstart
:state=1,scancodekeypressed=33,varequal=flashlight 1,etimergreater=500:setvar=flashlight 0,sound=audiobank\music\flashlight off.wav,etimerstart

:varequal=flashlight 0:mlightoff
:varequal=flashlight 1:mlighton,mlightfollowplr

;End of Script

Good work.

Marc, I tested out your code.

Do you want to know my EXACT reaction when I tried it out?

"Damn it!! ...AWESOME!!!

"

Your code is cleaner than mine, AND it manages to follow the player around perfectly even after respawning. I'm not sure what I was doing wrong with my code, but I know your code is perfect. Thanks!

Mind if I steal it? I'll give you full credit in the finished product and in any demos I make.

And yes, you may steal it.

Hmm, try this as a mod for your script Mando

+ Code Snippet

:state=0:DimVar=x_position,DimVar=y_position,DimVar=z_position,state=1

:always:setvar=x_position $PlrPosX,setvar=y_position $PlrPosy,setvar=z_position $PlrPosZ

:always:mlightx=%x_position
:always:mlighty=%y_position
:always:mlightz=%z_position

Personally I like to just direct it right at the player pos rather than a middle man variable, but either way works.

Marc, the timer in your script is to make sure holding f wont toggle faster than the user can react or even see? Try this:

:state=1,keypressed=33 1,:sound=audiobank\music\flashlight on.wav,mlighton,mlightfollowplr,state=2

:state=2,keypressed=33 0:state=3

:state=3,keypressed=33 1:sound=audiobank\music\flashlight off.wav,mlightoff,state=4

state=4,keypressed=33 0:state=1

;End of Script

Sorry if I butchered any code, havent looked at fpi in about 3 months :S

Also, if you want the flashlight to turn off when you die, add in a line that says:
:plrhealthless=1:mlightoff

I'm the exception to every rule, that rule withstanding
