:/

Well, I'm basically fucked. I can't learn without documentation, it just doesn't make sense for me ._.

[ZeekyHBomb]

It is pretty skippy, but basically you will have to learn by Valves code and the stuff you can find on their wiki.

Right, guess I'll ask something; why is a function clearly called "UploadFileAsync" in C# stopping the GUI from working until it finishes uploading?

[cpp]// blah blah blah crap above snipped

public partial class Form1 : Form
{
WebClient wcUploader = new WebClient();

public Form1()
{
InitializeComponent();

wcUploader.UploadFileCompleted += new UploadFileCompletedEventHandler(UploadFileCompletedCallback);
wcUploader.UploadProgressChanged += new UploadProgressChangedEventHandler(UploadProgressCallback);
}

private void button1_Click(object sender, EventArgs e)
{
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
string toUpload = openFileDialog1.FileName;
wcUploader.UploadFileAsync(new Uri("http://anyhub.net/api/upload"), "POST", toUpload);
}
}

void UploadFileCompletedCallback(object sender, UploadFileCompletedEventArgs e)
{
textBox1.Text = System.Text.Encoding.UTF8.GetString(e.Result);
}

void UploadProgressCallback(object sender, UploadProgressChangedEventArgs e)
{
textBox1.Text = (string)e.UserState + "\n\n"
+ "Uploaded " + e.BytesSent + "/" + e.TotalBytesToSend + "b (" + e.ProgressPercentage + "%)";
}
}[/cpp]

You're doing it wrong - it shouldn't.

[quote]
[cpp]
wcUploader.UploadFileCompleted += new UploadFileCompletedEventHandler(UploadFileCompletedCallback);
wcUploader.UploadProgressChanged += new UploadProgressChangedEventHandler(UploadProgressCallback);[/cpp][/QUOTE]

Quick hint: you don't need the new blahblahEventHandler() around the method group. C# will figure out what you mean without them.

[a2h]

[QUOTE=turb_;21689622]You're doing it wrong - it shouldn't.[/QUOTE]

Yeah... figured it out after a while that it was because the file I was uploading was tiny.

[i]However[/i], that doesn't solve the problem of why the GUI doesn't respond when the upload starts and finishes

I found a solution here [url]http://developer.valvesoftware.com/wiki/Compiling_under_VS2005[/url] One Problem is that i am using 2008 not 2005 and i am not compiling the sdk just parts of it i use a module for gmod. And that the solution wont help[/QUOTE]
Link against user32.lib.

Just chuck it in another thread:

using System.Threading;
new Thread( () => mywebclient.UploadFile(...) ).Start();

what?

Do you mean SetAbsVelocity?

[ZeekyHBomb]

You cannot do this on the client-side. Shared (client & server) will work best, or server only (will only preform good in singleplayer).
Also try VelocityPunch, iirc this one works well.

[raccoon12]

OK, what's wrong with it now?
it's in Server\source

[cpp]
#include "cbase.h"
#include "c_baseplayer.h"
#include "c_baseentity.h"
#include "c_basehlplayer.h"
#include "tier0/memdbgon.h"

void ForcePush()
{
CBasePlayer *ply = CBasePlayer::GetLocalPlayer();

trace_t tr;
Vector v_Begin, v_Stop, v_Dir;

AngleVectors(ply->EyeAngles(), &v_Dir);
v_Begin = ply->EyePosition();
v_Stop = v_Begin + v_Dir * MAX_TRACE_LENGTH;

UTIL_TraceLine(v_Begin, v_Stop, MASK_ALL, ply, COLLISION_GROUP_BREAKABLE_GLASS | COLLISION_GROUP_NPC, &tr);

if(tr.m_pEnt)
{
DevMsg("Entity hit");
CBaseEntity *ent = tr.m_pEnt;
if(tr.m_pEnt->IsNPC())
{
DevMsg("Entity is NPC");
ent->VelocityPunch(tr.plane.normal * -30);
}
}
}
ConCommand force_push("force_push", ForcePush, "Use the force", NULL);
[/cpp]

[ZeekyHBomb]

CBasePlayer::GetLocalPlayer()
On the server you will have multiple people. Even the single-player is coded on a networked structure to allow easier porting.
What you want is UTIL_GetCommandClient().

Also, next time post the error. It's better than having to guess ;)

[raccoon12]

There is no error, it just doesn't do anything to the zombie I spawn =(

also, it isn't a multiplayer mod

[ZeekyHBomb]

Try using a single collision group. I don't think they're meant to be used as flags.

Yeah, SetAbsVelocity. Damn Garry's Mod API messing my head.

[raccoon12]

Hmm... still doesn't work

[ZeekyHBomb]

If you put a DevMsg on top of the function, does it print that?

[raccoon12]

Tried that, here's what I have so far
[cpp]
#include "cbase.h"
#include "tier0/memdbgon.h"

void ForcePush()
{
CBasePlayer *ply = UTIL_GetCommandClient();

trace_t tr;
Vector v_Begin, v_Stop, v_Dir;

AngleVectors(ply->EyeAngles(), &v_Dir);
v_Begin = ply->EyePosition();
v_Stop = v_Begin + v_Dir * MAX_TRACE_LENGTH;

UTIL_TraceLine(v_Begin, v_Stop, MASK_ALL, ply, COLLISION_GROUP_NPC, &tr);

if(tr.m_pEnt)
{//
DevMsg("Entity hit");
CBaseEntity *ent = tr.m_pEnt;
if(tr.m_pEnt->IsNPC())
{
DevMsg("Entity is NPC");
ent->VelocityPunch(tr.plane.normal * -30);
//If that doesn't work, might as well try this
ent->SetAbsVelocity(tr.plane.normal * -30);
}
}
}
ConCommand force_push("force_push", ForcePush, "Use the force", NULL); // maybe I should set this to FCVAR_ something?
[/cpp]
No message comes up when I aim at a zombie, and I bound force_push to mouse1, same thing, nothing =(

[a2h]

OK, two questions related to C++:

1. What does (int*)foo mean?
2. What does &bar mean?

[Darwin226]

I think the second one means you are passing a reference to that variable instead of it's value so for example if you have a function like
void SetTo4 (int &x) { x=4; }

and call it with
int a=56;
SetTo4(&a);
cout << a << endl;

it would output 4.
Not 100% sure about that.

[ZeekyHBomb]

The first one does a C-style cast to a pointer to int on foo.
The second one uses the address-of operator on bar.

@raccoon12: Does it output something when you place a DevMsg at the top of your function?

[Agent766]

[QUOTE=Darwin226;21712503]SetTo4(&a);.[/QUOTE]

You only need SetTo4(a);

[Darwin226]

Ok, why do you need & for functions like scanf?

I'll check later today, busy at the moment

[a2h]

I'm trying to create an array to hold pointers to variables like this:

extern const u8 foo[];

Here's what my array looks like so far:

const u8* pl[] = {
	&foo,
	&bar
};

I'm getting this error: "cannot convert 'const u8 (*)[]' to 'const u8*' in initialization"

I've tried changing the u8* in the array to things like u8 (*)[] to no avail, any ideas? Thanks.

[ZeekyHBomb]

[QUOTE=Darwin226;21712977]Ok, why do you need & for functions like scanf?[/QUOTE]

scanf is a C-function and requires pointers, not references.

In the first snippet you have a const array of u8, in the second snippet you have a const array of u8 [i]pointers[/i].

[a2h]

[QUOTE=ZeekyHBomb;21713409]In the first snippet you have a const array of u8, in the second snippet you have a const array of u8 [i]pointers[/i].[/QUOTE]

But isn't that what I want to do? I want to stuff these variables which I have little control under due to the library I'm using into an array, but without using up more memory with a duplicate of the variable's contents.

[ZeekyHBomb]

In the first snippet you have an array of u8, not of u8 pointers tho.

[a2h]

[QUOTE=ZeekyHBomb;21713470]In the first snippet you have an array of u8, not of u8 pointers tho.[/QUOTE]

I tried adding [] to the end of the pointers in the array, but that caused "expected primary-expression before ']' token".

Bleh, I'm confused, off to sleep.
