[hlcoders] HitBoxes ?
Anyone notice when you run / crouch / jump etc The hit box is off? It seemed to do this is CS:S also and I thought it was a CS:S bug. However it is also doing the same thing in the MP SDK.. Anyone else notice this? r00t 3:16 CQC Gaming www.cqc-gaming.com ___ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders

[hlcoders] First-chance exception spam in Visual Studio Output window...
I was creating some Wiki documentation over the weekend and I wanted to start building a MOD from scratch so that I would have exact wording on Dialog boxes and whatnots. So, anywho, after deleting MyMod directory and deleting SteamApps\SourceMods\botman folder, and using Reset Game Configurations to flush everything from Steam. I Create a Mod in the C:\MyMod directory and name the mod botman. I open up Game_SDK.sln in Visual Studio .NET 2003, change to the Release SDK, build the solution, it copies the client.dll and server.dll to the Mods bin directory. I start things up from the Steam Play games dialog by double-clicking on my MOD name. Everything runs fine, I start the vehicles map, shoot my gun a few times, then quit. Then I switch to the Debug SDK solution, delete the client.dll and server.dll files from my Mod's bin directory, build the solution and the debug .dll files show up fine. I set the Debugger properties on the hl project to: Command: c:\program [EMAIL PROTECTED] 2\hl2.exe Command Arguments: -dev -game c:\program files\valve\steam\steamapps\SourceMods\botman -allowdebug ...right click on hl in the Solution Explorer and do Debug-Start new instance. Everything starts up fine, but I get (literally) thousands of exception messages... Microsoft C++ exception: common::CErrorCodeException It's been a few weeks since I ran a Mod in the debugger, but I don't seem to remember getting all that before, but I did remember somebody posting a message to this list about a month ago saying they were getting LOTS of exception messages, and I replied that you can turn off some of the exceptions using Debug-Exceptions in Visual Studio .NET 200, but you can only turn off stuff that Visual Studio recognizes (like stack overflow, illegal instruction, or array bounds exceeded, etc). common::CErrorCodeException is something being raised by the engine and isn't something I can turn off. I did notice that if I create a server plugin for a Valve game (like CS:S or HL2DM), I get a few common:CErrorCodeException messages when starting up, but I don't get the 1000's of message that I get when I start my own MOD. So, to make a long post even longer, does everybody get 1000's of these execption messages in the Visual Studio Output window when running their MOD in the debugger, or do I just have something not set up right? P.S. I did try adding -steam to the Command Arguments before starting the debugger, but that doesn't seem to make a difference, I still get the same behavior. -- Jeffrey botman Broome ___ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders

[hlcoders] Objects, Physics, and Gravity Concepts
With the introduction of the physics engine in HL2, I'm curious if there is someway to have gravity affect physics? In HL2 SP, I noticed it really doesn't. How? Well, you could pull out a pistol and still snipe with it... there is no gravity play on it (no arc). But, then again, tossing other objects (cans or boxes), it does. So, the point to the question, is if a sports MOD (e.g. football style) could be made to where the ball is thrown like an object or bullet from a gun and have gravity affect it's physics? Then, take the same thing, and adjust the gravity setting to a more low-gravity setting, would the gravity and physics change (e.g. football in space)? Also, is there a way to specify the center of gravity with possibly an entity for mappers to place in a map? For example, having an asteroid with gravity in it's center allowing you to walk around it and still be on the ground, rather than having a world is flat type of feeling. Not sure if anyone has been testing things like this, if so, some input on your findings would be nice to hear.

Is it possible to add a fundamentally new movement, e.g. rotate about an axis passing through center of player and orthogonal to player's plane (if one were floating in space rather than standing)?

Re: [hlcoders] Objects, Physics, and Gravity Concepts
Not that I'm personally facing this problem, but wouldnt you be able to do a simple distance check and have the hitscan move down depending on how far it traveled and the gravity. The only problem I could see with this is that hitscan is a line and it would actually modify the trajectory of the bullet out of the barrel but there must be some way around it. Just providing a few suggestions. If you can't fix the bug, you might still have something relativly convincing...

RE: [hlcoders] new movements
All of the code for player movement is in the SDK. Take a look at game_shared/gamemovement.cpp -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Ettinger Sent: Monday, January 03, 2005 8:02 PM To: hlcoders@list.valvesoftware.com Subject: [hlcoders] new movements Hello All, Are the basic movements of strafing and forward/backward built into the engine? Is it possible to add a fundamentally new movement, e.g. rotate about an axis passing through center of player and orthogonal to player's plane (if one were floating in space rather than standing)? I've been trying to step through the basic movements and run up against engine stuff which is not exposed in the source code. Or am I missing something obvious?

RE: [hlcoders] Objects, Physics, and Gravity Concepts
The easiest way to do this is to turn bullets into projectiles. In HL2 they are a single raycast. But in your mod you could decide how fast they travel and sweep a ray over each tick from the previous position to the current position of the projectile. You could add gravity easily enough. This will still approximate the motion in each tick with a line, but you could subdivide further if you really need more curvature. If the linear speed is high enough compared to gravity or the tick rate is high enough there won't be much error with one segment per tick. // simplest per-frame integration function Vector newPosition = oldPosition + velocity * dt; Velocity += gravity * dt; UTIL_TraceLine( oldPosition, newPosition, ... Or you could even use vphysics objects if you want to spend a bit more memory CPU on each bullet. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Menard Sent: Monday, January 03, 2005 8:17 PM To: hlcoders@list.valvesoftware.com Subject: Re: [hlcoders] Objects, Physics, and Gravity Concepts Not that I'm personally facing this problem, but wouldnt you be able to do a simple distance check and have the hitscan move down depending on how far it traveled and the gravity. The only problem I could see with this is that hitscan is a line and it would actually modify the trajectory of the bullet out of the barrel but there must be some way around it. Just providing a few suggestions. If you can't fix the bug, you might still have something relativly convincing...

I think it probably depends on how fast you want the bullets to move through the air. If you make bullets a true entity (with gravity and collisions, etc), then you have to update their location as they move through the world (applying gravity, checking for collisions, etc.). Calculating the height change due to gravity over a given period of time is pretty straight forward high school physics (use google.com if you want the math). The real issue is that things that move VERY fast through the world don't get their position updated often enough to follow the path of a true parabola. You get something like this (excuse the ASCII graphics)... Game Ticks (StartFrame) at the 'v's v v v v x--x /\ / \ /\ / \ /\ / \ /\ x x The 'x' object follows the path of a parabola but because you are not ticking the engine at 1000's of times per second, you wind up with discrete locations along the curve (at the points in time where you can calculate where the entity will be at that time). If you are only checking for collisions at these points in time (or doing line/hull checks from the previous point in time to the current point in time), you will miss hitting entities that don't lie along your discrete path (like at the top of the arch in this case). You can modify the calculations so that you do your own stepping between discrete points in time to create a true parabolic curve and do your own collision checking to see if an entity was collided with, but this can be somewhat time/CPU consuming.

In FPW view is it possible to change where the view is? For example if you look at your monitor you can see on the sides but they are somewhat out of focus. I am trying to do something like this create a wider view and blur the sides a little.

Re: [hlcoders] Firstperson weapon view
Maybe im not explaining it right. FOV (field of view) when changed via the console FOV 20 it seems to zoom in.. FOV 90 zooms out. What I wanted was a wider type view? A peripheral view so you can see to the sides more instead of being boxy like.
