[QUOTE=Two-Bit;39091846]Hello gentlemen, Being new to C++ I ma having some trouble with switch statements. I am in the process of making a tic tac toe game (very basic). I have the user input an x and a y coordinate (for instance tc is top centre, br, bottom right).
I am using switch statements to resolve the answer but I am not sure if I am using them correctly, it is also my first attempt at using functions so I have most likely misunderstood how they work. Apologise for the noob and probably poorly written code but if you wish to help me out here is.

Thank you very much ^.^[/QUOTE]

A few things:

* The variables that represent the places in the board are local to the function Board(), they will be generated every time the function is run (And if the function worked it would generate a new, blank board every time), and cannot be accessed outside of the function. Your switch statement can't access them, they should be on the global scope (Outside of all functions).
* Board() is declared as returning a string, but it doesn't return anything, so it should be void.
* place1() is declared as returning an integer, but it also doesn't return anything, so it should be void
* that while() loop needs to be something like:

[CPP]
while(test) //No semicolon!
{
//...code
}
[/CPP]
* Switch can only be used with integers in the parentheses (char, short, int, long, long long). The statement might check out on [I]some[/I] compilers, because strings are also technically integers in a way you really don't need to understand right now. You need to use a series of if...else statements.

Working with lwjgl on a doom style dungeon crawler. I have moved the main rendering game viewport up a bit, leaving space at the bottom for the HUD to be rendered and the game will be rendered above that ( its an 800x600 window ).

To do this I used glViewport after I set up all the perspective view stuff in the initialization. Now how do I set up a seperate rendering loop and coordinate system and stuff for that area down in the bottom now? I want to have an orthographic thing going on so I can draw my HUD.

Is there any comprehensive guide to programming games. I don't quite understand how to communicate between classes in a good way. I also don't get how I would best implement menu screens, popups, overlays, or anything that is not just the bare game screen.

Preferably in Java but I could work with a general guide.

[Darkwater]

If you're stuggeling with menus, try to make everything show up in the gamefield, eg. walk here to start, walk over there to see the options, etc.

I always wondered the same thing. What I found out was that there is no "guide" for that stuff. You just learn it over time. Look at game sources, game examples, and follow tutorials.

There really is no "correct" way to do things in game programming. There are efficient and non efficient ways. It is up to you to figure out which way works best for your current situation and go with it.

Learning game programming is learning (almost) everything there is. Start small. Write an addon for GMod, then a Source Engine mod. Slowly go up the ladder.

For people disagreeing, I got the same error with using SFML 2.0 on VS12 and I had to recompile SFML for it, and that fixed it. I'm pretty sure SFML 2.0 only has 08 and 2010 compiled in the download.

I've always wondered, what does source engine coding entail? I've been curious, as I always thought when a mod leader was looking for a programmer, and since I'm comfortable with C, then I could probably learn it.

Entities, game hooks (like CalcView for view alterations), weapons, gamemodes, UI, AI, and a lot more stuff.

Once I'm done with an SFML game I'm working on I might actually look into that; I've always wanted to work with a team and be a part of something; it also gives me some initiative to work.

Thanks!

[Dooskington]

Oh yeah, that is actually a great idea.

I would start with a gmod gamemode and then make a source mod, that will get you on the correct path :)

You can learn Lua in an afternoon pretty much.

Just check out [url]http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/index2bde.html[/url] and see what you think.

[stringy]

The first edition of [URL="http://www.lua.org/pil/"]PIL[/URL] is free and was a joy to read if you are interested in learning Lua. Might be overkill for just a bit of gmod Lua, but even if you don't use it the language is really interesting.

[QUOTE=A big fat ass;39088057]I'm very new to VB, and I want to make a program where the user can choose and replace one file on their system with another. I'm thinking of how to do it, and I'm having some trouble. I think a combo box would work great for selecting the files, but I'm having some difficulty in figuring out how to put variables in the combo box instead of just strings.[/QUOTE]

In VB.NET this should be extremely easy.

Code off the top of my head..

Sub Button_click() Handles YourButton.Click
Dim fileToReplace As String
                'show the file dialog
                Dim ofd As New OpenFileDialog()
                'picking file 1
                If ofd.ShowDialog() = DialogResult.OK Then
                    fileToReplace = ofd.FileName
                Else
                    'the user didn't pick a file, handle it
                    Exit Sub 'make sure the ofd isn't shown again, and the sub doesn't continue
                End If


                'picking file 2
                If ofd.ShowDialog() = DialogResult.OK Then
                    FileIO.FileSystem.WriteAllText(FileIO.SpecialDirectories.Temp & "\tempfile", FileIO.FileSystem.ReadAllText(ofd.FileName), False)
                    'in the above line, I copied one of the files were going to be replacing to a temp file, so we can access it later
                    FileIO.FileSystem.WriteAllText(ofd.FileName, FileIO.FileSystem.ReadAllText(fileToReplace), False) 'Relace the file we just picked with the original file
                    FileIO.FileSystem.WriteAllText(fileToReplace, FileIO.FileSystem.ReadAllText(FileIO.SpecialDirectories.Temp & "\tempfile"), False)
                Else
                    'the user didn't pick a file
                    Exit Sub
                End If
End Sub

Tested and works perfectly. Preserves file names.

Lua Question!

If I quickly assign something like:
[lua]
fStart = a,b,c
[/lua]

How can I come back later and compare the 2 value of fStart to something else:

[lua]
if b == fStart then
end
[/lua]

The above function simply will compare the first value with 'b'. How do you compare the second and third value individually with out having to compare like:
[lua]
if a,b,c == fStart then
end[/lua]

Thanks in advance!

It looks like you are confusing multiple assignment and tables.

Multiple assignment:
[lua]local a, b, c = 1, 2, 3 -- a = 1, b = 2, c = 3
local f = 4, 5, 6 -- f = 4. Note that 5 and 6 are discarded[/lua]

Tables:
[lua]local f = {a, b, c}

if f[1] == a then -- f[2] = b, f[3] = c
-- do something
end[/lua]

The elements of a table can be accessed with square brackets like above.

Im trying to add in animations for ironsights which is triggered by a button for my mod. Ive already defined and added the buttons and so on, but now I am just trying to trigger animations to play when the button is pressed. This is what I have in basecombatweapon_shared.cpp under void CBaseCombatWeapon::ItemPost

[CPP] if ( pOwner->m_nButtons & IN_IRONSIGHT )
{
IronSight();

if ( !bIronsighted && (pOwner->m_nButtons & IN_IRONSIGHT ) )
{
bIronsighted = true;
SendWeaponAnim( ACT_VM_IRON_IDLE );
m_fIronsightedReady = gpGlobals->curtime + GetViewModelSequenceDuration();
}

else if ( bIronsighted && !(pOwner->m_nButtons & IN_IRONSIGHT ) )
{
bIronsighted = false;
SendWeaponAnim( ACT_VM_IDLE );
m_fIronsightedReady = gpGlobals->curtime + GetViewModelSequenceDuration();
}

if ( bIronsighted )
{
if ( gpGlobals->curtime > m_fIronsightedReady )
{
bIronsighted = true;
SendWeaponAnim( ACT_VM_IRON_IDLE );
m_fIronsightedReady = gpGlobals->curtime + GetViewModelSequenceDuration();
}
return;
}
else if ( bIronsighted )
{
if ( gpGlobals->curtime > m_fIronsightedReady )
{
bIronsighted = false;
SendWeaponAnim( ACT_VM_IDLE );
m_fIronsightedReady = gpGlobals->curtime + GetViewModelSequenceDuration();
}
return;
}

}[/CPP]

But it doesnt do anything, any help?

[SteveS]

That might be the worst ironsight implementation I've seen yet (also editing base classes... yuck). The reason it won't do anything (or might jitter) is because it will then attempt to play the idle animation.

Check the relevant code for where the idle animation is set.

So I'm trying to implement real-time events into a game I'm working on... What is the best way to track time in Java, and execute events occasionally? (Such as weather change, etc)

Right now I've got a clock working with the Java Date class and I update it after a change between System.CurrentTimeMillis(), but is there a better way?

Thanks

I get that, but what if, say, I wanted an event to happen at 2PM, and the user exited the program at 1:50? I guess I would just save the date on program close and do a comparison to that when it opens?

I... think I just answered my own question... Thanks :P

On a new note, are there any good articles on object serialization you guys can recommend?

I need to find out, specifically, the formula for Mario's Fireball bounces. When they hit a level surface, it's only 45° that it bounces at. If the surface, itself, is at an angle, it bounces at an angle that is slightly higher than the angle of the surface (by about 5° to 15°).
What I need to know, is how to figure out the correct displacement. On level surfaces, the most it can bounce to is 90° additions to a 45° turn.
I shouldn't need trigonometry to figure this out. All I should need is the surface normal, and arithmetic.

I just would like to know from some of your personal experiences what worked the best into starting Android development.

That book definitely isn't a bad place to start. Of course a lot of things (if not everything) you need to learn about programming can be found online, but sometimes it's nice to have a book to go through (in my opinion).

And since you have it anyway, why not give it a read? If it doesn't work for you, then come back, (and maybe say what part of the book didn't work for you, that would help)

Easier to help with: Is physcollide data.HitNormal.z on a scale of 90? Such as this:
1.0=-90, 0.5=-45, 0=0, -0.5=45, -1.0=90
or
1 = Straight Up, 0 = Level to gravity, -1 = straight down.
Or is it reversed. since -90° is UP, and +90° is DOWN in Source? Thus, -1 is up, and +1 is down... 0 is still level to gravity.
