Controller issue AGAIN

[Raul]

After doing the wiki tutorial and read one more time the article from Resources I thought I managed the Controller. But there are some problems:

 

I made a little scene in the Editor. Testing with the fpsshooter script is ok. The character is correctly moving and sliding. The coll detection works fine with all the object.

In my game the controller is jumping back when hitting a wall/fence and sometimes is going through them.

 

This is my code:

 

Create Player:

	
PlayerController=CreateController(1.8,0.45,0.25,46);
EntityType(PlayerController,1);
SetBodyMass(PlayerController,10);

 

Update Player:

 

mx=Curve(MouseX()-GraphicsWidth()/2,mx,6);
my=Curve(MouseY()-GraphicsHeight()/2,my,6);
MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2);
PlayerRotation.X=PlayerRotation.X + my/10.0;
PlayerRotation.Y=PlayerRotation.Y - mx/10.0;

PlayerMove=KeyDown(KEY_W)-KeyDown(KEY_S);
PlayerStrafe=KeyDown(KEY_D)-KeyDown(KEY_A);

if (KeyDown(KEY_LSHIFT)||KeyDown(KEY_RSHIFT)) {
	if (!ControllerAirborne(PlayerController)) {
		PlayerMove*=2.0;
		PlayerStrafe*=2.0;
	}
}

float PlayerJump=0.0;
if (KeyHit(KEY_SPACE)) {
	if (!ControllerAirborne(PlayerController)) {
		PlayerJump=6.0;
	}
}

//Set controller input
UpdateController(PlayerController,PlayerRotation.Y,PlayerMove*3,PlayerStrafe*3,PlayerJump,50);

PlayerPosition=EntityPosition(PlayerController);
PlayerHeadPosition=PlayerPosition;

PlayerHeadPosition.Y = Curve(PlayerPosition.Y+1.8,PlayerHeadPosition.Y,4);
PlayerHeadPosition=Vec3(PlayerPosition.X,PlayerHeadPosition.Y,PlayerPosition.Z);

 

I alos tried the technique from the script (calculating the Strafe and Move using the Curve) but in that case the controller cannot be controlled. It simply goes trough objects

 

Also I noticed a thing. My controller has 1.8 height.

 

If set the PlayerHeadPosition.Y = PlayerPosition + 1.8, when in debug mode I saw the head (also the camera) is in the middle of the controller..

[Rick]

I seem to recall that really skinny bodies, like your fence probably, don't always work correctly.

 

Take the Curve() off when setting the position of the camera once and see if that helps.

[Canardia]

You should not make walls and fences 0 mm thick, but as thick as they are in real.

[Raul]

Rick: I removed the Curve and now its ok. Where is the problem in this case? I still want to use this function (Curve)

 

Rick + Lumooja: The fence is taken from the Assets gallery. But the problem is that I have that "jumping back" also when hitting a wall which is not 0 mm Its true is not as bad as fence back but is still there.

 

But why playing the editor is working fine and smooth and in my game sucks?

 

p.s:

 

The physic bodys are not 0 mm.

[Rick]

Why do you want to use that function for the height of the camera? Shouldn't that just be a certain value all the time? Do you have some gameplay thing in there where you want to change it's position with Curve()?

[Canardia]

When you walk, your head bobs up and down using a curve (with a steeper curve when your leg hits the ground). Even in LCP1 we have that. I tried also swaying around the Z axis, but I got seasick, so I disabled it. And you don't rotate around the Z axis much at all when walking or running.

 

The code is very simple, but it adds a great realism to any game (also 3 different footstep sounds):

double walkadd=AppSpeed()*Length(GetBodyVelocity(game.scene.GetCurrentPlayer()->body));
walktimer+=walkadd;
game.scene.GetCurrentPlayer()->eyeoffset.Y=Curve(1.0-0.4*sin(walktimer/500.0),game.scene.GetCurrentPlayer()->eyeoffset.Y,16);
if(walktimer>125)
{
walktimer-=125;
string i="";
i=49+(int)random(0,3);
EmitSound(game.scene.GetCurrentPlayer()->body,LoadSound((str)string("abstract::walk"+i+".ogg").c_str()));
}

[Raul]

@Rick: this function helped me when climbing up the stairs to not have a violent climbing..

 

@Lumooja: I will try right away your code.

[Rick]

I can't stand head bob in games. It always makes me sick. The fact that it's more real means very little to me in games where I have 5 people shooting at me from 20 yards and I'm getting hit but my "armor" helps me kill them.

[Canardia]

It's pretty nice and doesn't make you sick when it's done right, and not unnaturally. And if someone still gets sick from it, then he's obviously not a good player as he can't stand some battle rumble So the advantage goes to the players who can stand more.

 

It's the same with other game aspects too, I plan to make a game which is so scary that you can't play if you're too scared to play it It should have also 3D sounds, so you can't play it if you don't use headphones or have a decent 8.0 surround system.

 

Games need a challenge to be fun, and lots of different challenges. I'm just playing C&C 95, and it's also damn challenging because the enemies zerg your base all the time, but that's what makes it fun.

[Raul]

@Lumooja: your code is working (at least is an alternative to my simple Curve utilization) BUT no head bobs effect is present. I dont really want this effect but I am just afraid I am doing something wrong.

 

Also another strange thing happen. I have a crate (an ammo box). If I set its collision to "Prop" when I go near it, it simply throw me away through walls for a long distance

[Canardia]

Make sure the player has mass 60, and the objects around 1-5 if you want to push them.

[Raul]

You should see this... I changed the box mass to 5 from 10. Now when I hit it, sometimes is throwing me away, sometimes the box is jumping and flow in the air :| until I hit again.

 

I have the gravitation set to 0, -20 , 0

 

p.s.

The player has the mass 80

[cassius]

I had this problem but found that it was because I had not updated the files in my project folder when i did the last update.

Worked perfectly after I did so. Maybe not your problem, I don't know.

[Raul]

Nope. Its not that.

 

I made a short video (sorry for the 50mb length but i have no converter..) showing my problem:

 

www.rvlgames.com/bug.avi

[cassius]

I found that a mass of 60 worked too well for me. a mass of 30 looks more natural in mt case rvl's description is exactly what I was getting.

[Raul]

with 30 is awful.

 

I put 60. Its better but still my controller is shaking when hitting any object. Its shaking and from time to time is throwing me away (

[Raul]

EDIT:

 

same behavior. even if I use 30 or 60 or any number. Sometimes the Controller is throwing away, sometimes the objects are...

[cassius]

This line can also be relevant, particularly the iteration param.

 

UpdateController(player, camrotation.Y, move * 5.5, strafe * 5.5, jump, 500,10)

[Raul]

Negative. Same thing.

 

Imagine 2 cars coming with full speed one into another. This is happening with me and the objects when touch them.

[cassius]

My problem was that the objects hit by the controller fell toward the controller and when pushing against crates they flew behind the controller rather than in the direction pushed. Sometimes the controller would pass thru the level walls and fall out of the game. But as I said updating le solved the problem

Actualy I was using the wrong updater at first, and not the latest one.

[Raul]

I see. Same behavior happens to me. Sometimes I fall out my map too. I have just one updater, mailed me by Josh 4 days ago.

[Raul]

I have uploaded 2 little movies about my problem.

 

Also this is a simplified version of my code:

 

PLEASE I really want to know where is the problem. I simply cannot make anything with this issues (

 

#include "engine.h"

void InitLeadwerks()
{
Initialize();
SetAppTitle("Game");
Graphics(1024,768,0,0,GRAPHICS_BACKBUFFER+GRAPHICS_DEPTHBUFFER);

RegisterAbstractPath("data");

SetTextureQuality(1);
TFilter(1);
AFilter(MaxAFilter());
}

int main(int argc, char** argv)
{
InitLeadwerks();
CreateWorld();

//The Framework
TFramework framework=CreateFramework();

TLayer myLayer = GetFrameworkLayer(0);
   TCamera frameworkCam=GetLayerCamera(myLayer);

   //Set Lua variable
   BP L=GetLuaState();
   lua_pushobject(L,framework);
   lua_setglobal(L,"fw");
   lua_pop(L,1);

TController player=CreateController(1.8,0.4,0.5,45.01);
EntityType(player,1);
SetBodyMass(player,10);
PositionEntity(player,Vec3(0,10,10));
DebugPhysics(1);

   // Setup map/scene
   LoadScene("abstract::map1.sbx");
Collisions(1, 1, 1);
   Collisions(1, 2, 1);

   HideMouse();
   MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2);


SetWorldGravity(Vec3(0,-20,0));

float move=0.0;
float strafe=0.0;

//Main loop
while(!KeyHit(KEY_ESCAPE)) {

move=KeyDown(KEY_W)-KeyDown(KEY_S);
strafe=KeyDown(KEY_D)-KeyDown(KEY_A);
UpdateController(player,0.0,move*3,strafe*3,0,40);
	//RotateEntity(frameworkCam,myPlayer.PlayerRotation);
	PositionEntity(frameworkCam,Vec3(0,5,0));

       UpdateAppTime();
       UpdateWorld(AppSpeed()) ; 

	//PositionEntity(frameworkCam,myPlayer.PlayerHeadPosition);

       UpdateFramework();
       RenderFramework();


	Flip(0);

}

//Stop the engine and free the dll from memory
Terminate();
return 0;
}

 

In the videos you can see how the objects are simply jumping around like crazy. This happens sometimes to my controller too. I tried all kind of mass settings. No result.

[Canardia]

These lines are not needed and may cause wierd physics behavior:

        UpdateAppTime();
       UpdateWorld(AppSpeed()) ; 

UpdateFramework does those commands already.

[Josh]

The only time I have experienced a controller being "thrown" with great force was when the physics geometry had some one-sided surfaces it was moving into from behind.

 

If you want help, please post an example we can run that demonstrates your problem. Otherwise we are just speculating about what it might be.

[Raul]

If their is a supra natural force somewhere in this Universe then: THAT FORCE BLESS you Lumooja

 

Thanks you to all for helping me. You to Josh
