Help needed to create a Grimrock style camera (dungeon crawler)

SkyNet00

Me and my bro during our spare time are doing some graphic for a simple dungeon crawler game, but we really suck at programming. I need some help to create a camera like Dungeon Master, Eye of the Beholder, Grimrock (90 degree step-by-step camera).

I have spent some time to sort it out "bIgnoreLookInput=true and bIgnoreMoveInput=true" must have a value of 1 or 0 not true or false, because otherwise the script won't compile, however even with those properties the mouse is still 100% working. also the binded keys are not working;

i made a PlayerController like this:

Class MyPlayerController extends PlayerController;

defaultproperties
{
bIgnoreLookInput=1
bIgnoreMoveInput=1
}

simulated exec function LookRight()
{
ClientSetRotation(Rotation+MakeRotator(0, 16384, 0), true); // Add 90 degrees to your rotation
}

simulated exec function LookLeft()
{
ClientSetRotation(Rotation+MakeRotator(0, -16384, 0), true); // Subtract 90 degrees
}

simulated exec function MoveForwards()
{
Pawn.SetLocation(Pawn.Location+Vector(Rotation)*25 0); // Teleport 250 units forward in the direction you're facing
}

simulated exec function MoveBackwards()
{
Pawn.SetLocation(Pawn.Location+Vector(Rotation)*-250); // Teleport 250 units backwards in the direction you're facing
}

I added the lines to the GBA "section" in DefaultInput.ini:

.Bindings=(Name="GBA_MoveBackwards",Command="MoveBackwards")
.Bindings=(Name="GBA_MoveForwards",Command="MoveForwards")
.Bindings=(Name="GBA_LookLeft",Command="LookLeft")
.Bindings=(Name="GBA_LookRight",Command="LookRight ")

and i added these lines to "Game Keyboard/Mouse Bindings" section in the "Primary default bindings" on the same file(DefaultInput.ini):

.Bindings=(Name="D",Command="GBA_LookRight")
.Bindings=(Name="A",Command="GBA_LookLeft")
.Bindings=(Name="W",Command="GBA_MoveForwards")
.Bindings=(Name="S",Command="GBA_MoveBackwards")

Now; the script compiles perfectly but in game nothing works, how can i fix this please??:poly124:

That's kindof a big question. You're trying to do too much all at once. Gotta take it one step at a time, that way you can tell at what point stuff breaks.

When you say nothing works, what exactly do you mean?

Can you tell if it's even using your PlayerController class? That should be the first step. Insert some `log() lines at key events so that you can tell if they get fired off.

Gotta find exactly where things break.

SkyNet00

hi, please can you show me an example of how to `log() inside MyPlayerController Class?
i told you we suck at programming =_=.....this is our first attemps.
we really appreciate your help^^

SkyNet00

ooooooooookkkkk now it half works, mouse is looked and the camera turns by 90 degrees left/right, BUT it doesent move forwards and backwards.
I accomplished this by adding a custom world info; yet i dont know how to use the logs

Bigjohn

Simply add a line like this:
`log("========================Variable content:" @ myVar);

Anywhere in your code. Say in your exec function, or anywhere really. The equal signs are just so the line is easier to see in the log among all the other lines. myVar is any variable you wanna keep track of. And it's optional. You could just output some text like this:
`log("===============Some text=========");

This will output a line in the log. This is how I do basic debugging. If I need to see what the value of a variable is when a certain function is called, etc. Or if the line doesn't appear in the log at all, then I know the place I put it in never gets called.

hi, i made a couple of logs, here the code that i compiled:

Class MyPlayerController extends PlayerController;

defaultproperties
{
bIgnoreLookInput=1
bIgnoreMoveInput=1
}

simulated exec function LookRight()
{
ClientSetRotation(Rotation+MakeRotator(0, 16384, 0), true); // Add 90 degrees to your rotation
}

simulated exec function LookLeft()
{
ClientSetRotation(Rotation+MakeRotator(0, -16384, 0), true); // Subtract 90 degrees
}

simulated exec function MoveForwards()
{
`log(Pawn.SetLocation(Pawn.Location+Vector(Rotation)*250)); // Teleport 250 units forward in the direction you're facing
}

simulated exec function MoveBackwards()
{
`log(Pawn.SetLocation(Pawn.Location+Vector(Rotation)*-250)); // Teleport 250 units backwards in the direction you're facing
}


and i recaived this log:

but i try to log also the first two functions (the only two that are actually working) the script wont compile and i receive 2 errors.

from the log i cant understand a single thing, can you help me to read this?
what do you see behind the matrix??

hi all, this is not a bump but an update lol....

in order to make all things(half work)i forgot to mention that i had to add the "game rules" through a custom world info; however the whole thing is still just half working(only left/right and mouse locked).

if you need more info i also start another conversation on UDK forum
(sorry this is not advertising i'm doing this due the lack of documentation about this topic, sry if is against the rules just remove this link)

I have a short cut for UDK that has the target set to this:
C:\UDK\UDK-2012-05\Binaries\UDKLift.exe editor -log

When the editor is launched it's going to launch a log window too.
When you play in the editor the log will show all the script logs (and kismet, also some problems that might be happening in script).

For your code, you need to isolate what is the specific problem it seems.
To do that I would add logs throughout each function to see what's going on. For example:

simulated exec function LookRight()
{
ClientSetRotation(Rotation+MakeRotator(0, 16384, 0), true); // Add 90 degrees to your rotation
`log("LookRight function is firing");
}

and do that to all the ones that aren't working.
In the play in editor (or game, if you have the short cut set-up to show the log in the game) hit d, or whatever calls 'lookright'.
In your editor log you should see something like, "script log: LookRight function is firing"
If you don't see this, then for whatever reason your function isn't firing (your log's not being called).

If you do see the log, then you know the function is being called, but there's something wrong with the code.

If that's the case, I would go through the line of code with logs finding out what all the variables values are.
Figure out why it's not doing what it's suppose to.
Is there a variable that isn't what I want/thought it was? what is the value of (Rotation+MakeRotator(0, -16384, 0)? Are these what they're suppose to be?

As already mentioned you would do this to log a variable:
`log("The variable I want is : "$VariableName);
the script log would look something like this:
scriptlog: The variable I want is : 30
(3o is the value of 'variablename')

I would basically go through and try to find out exactly what's going on until I can isolate what the root cause of the problem is.

Hope that helps a bit

Your move forward and backward arguments are calling on a pawn.
What pawn?
The script has to know what to move when you invoke the command.

Take a look at the existing player-controller movement functions and see how the player pawn is passed in there.
