Script question

[Winnyfred]

Ok, I found a Mission_setFriendlyEjectPickup, is this used to make certain nav points friendly eject pickups, or the entire mission friendly eject pickup.

 

[eddieb]

Entire mission, but you change it every nav point if you like. It's the latest setting that is used. But you only really need to set it once.

 

[Winnyfred]

Here is another one for you all to solve, this time it is a cutscene:

<?xml version="1.0" encoding="UTF-8"?>
<mission name = "" sector="blue" can_eject="false" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="mission.xsd">
<navpoints number="1">
<navpoint numships="3" numwaves="1" name="nav1" >
<ship name="midway" comm="" autopilot="false" land="true" alignment="friend" wave="0">
<location>
<point x="2.6711185" y ="0.0" z ="-261.76962" />
</location>
<rotation>
<point x="0.0" y ="0.0" z ="0.0" />
</rotation>
</ship>
<ship name="sar" comm="" autopilot="false" alignment="friend" wave="0" scriptid="sar">
<location>
<point x="18.69783" y ="0.0" z ="-48.08013" />
</location>
<rotation>
<point x="0.0" y ="0.0" z ="0.0" />
</rotation>
</ship>
<ship name="vampire" pilot="player" comm="" autopilot="true" alignment="friend" wave="0" scriptid="player">
<location>
<point x="66.77796" y ="0.0" z ="-227.04507" />
</location>
<rotation>
<point x="0.0" y ="0.0" z ="0.0" />
</rotation>
<script oncreate="printlocation" />
</ship>
<script oncreate="nav1_create" during="nav1_during" />
</navpoint>
</navpoints>
</mission>
Now here is the cutscene part:
dofile "flightcommander.lua"

function nav1_create()
start_time = Mission_getElapsedTime();
focus = start_time + 2000
donetime = start_time + 25000
end

function mycallback()
end

function nav1_during()
now= Mission_getElapsedTime()
if not started then
if now > start_time then
Music_play("Saviour_Dead.mp3");
Cutscene_start("mycallback");
Overlay_setEnabled(true);
Overlay_setText("...Death was the price S*****r paid, but he saved hundereds.")
Ship_setAIEnabled("sar", "false")
Ship_MaxVelocity ("sar", 100.0)
Ship_SetDesiredVelocity("sar", 4.0)
Camera_setCameraType(CAMERA_AUTOPILOT)
Camera_setFocuseShip("sar")
end

else

if now > donetime then

Mission_exit()

end
end

end

What do you see wrong in it? I have checked it over and over, and FC does not see anything wrong, and it just crashes. Mabye you all see something wrong?

 

[eddieb]

I see a couple of bugs right away:

1) You never set started to true or false. You need to take care of initializing it, then setting it after you do actually get started

2)
Ship_setAIEnabled("sar", "false")

Is wrong
The second parameter is a boolean, NOT a string.

 

[Winnyfred]

eddieb, are you sure I need to say

Cutscene_start(true, "mycallback")? Because your script example doesn't do that...

 

[eddieb]

Look at my cutsceneexample.lua. I do call Cutscene_start. Read the scripting documentation, Cutscene_start only takes 1 parameter, not 2.

 

[Winnyfred]

Ok I did that and it still will not work here is an updated version:


dofile "flightcommander.lua"

function mycallback()
end

function nav1_create()
start_time = Mission_getElapsedTime();
donetime = start_time + 27000;


end

function nav1_during();
now = Mission_getElapsedTime();
if not started then
if now > start_time then
Music_play("Saviour_Dead.mp3");
Cutscene_start(true, "mycallback");
Overlay_setEnabled(true);
Overlay_setText("...Death was the price Saviour paid, but he saved hundereds.");
Ship_setAIEnabled("sar", false);
Ship_setMaxVelocity("sar", 150.0);
Ship_setDesiredVelocity("sar", 1.0);
Camera_setCameraType(CAMERA_AUTOPILOT);
Camera_setFocusShip(true, "sar");
started = true;
end

else
if now > donetime then
Mission_exit();
end
end

end

I have compared it to yours eddieb, and it looks like everything is in order, yet its still a crash to desktop, and I think it has something to do with the camera... or the disable AI, but I can't figure out what it is.

 

[eddieb]

First: run from the command line, that may help you debug.

Everything isn't in order, you still have the wrong number of parameters for Cutscene_start and Camera_setFocusShip. You should look at my scripting documentation page to confirm this. Also, as I said before, you never initialized started.

AH HA! I finally got it, I was missing a function and now it is working.
