Controller

[MrIslomaniac]

I just made a new Player class for me but my controller now does not seem to work anymore, it just get stuck in the air where it is created(neither gravity nor collision).

I also tried the tutorial for controllers, but that does not work either ... any clues?

#include "engine.h"
int main(int argc, char** argv)
{
Initialize();
//Create a graphics context
Graphics(800,600);
//Create a world
if (!CreateWorld()) {
MessageBoxA(0,"Error","Failed to create world.",0);
goto exitapp;
}
//Create a camera
TEntity cam=CreateCamera();
CameraClearColor(cam,Vec4(0,0,1,1));
PositionEntity(cam,Vec3(0,2,-10));
Collisions(1,2,true);
//Load a model
TModel scene=LoadModel("scene.gmf");
if (scene==0) {
MessageBoxA(0,"Error","Failed to load model.",0);
goto exitapp;
}
EntityType(scene,2);
//Create a light
TLight light=CreatePointLight();
PositionEntity(light,Vec3(0,5,0));
//Create a render buffer
TBuffer buffer=CreateBuffer(800,600,BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL);
TController player=CreateController();
EntityType(player,1);
SetBodyDamping(player,0.0);
SetWorldGravity(Vec3(0,-20,0));
float move=0.0;
float strafe=0.0;
TVec3 camrotation=Vec3(0);
float mx=0;
float my=0;
HideMouse();
MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2);
//Main loop
while(!KeyHit(KEY_ESCAPE)) {
//Camera looking
mx=Curve(MouseX()-GraphicsWidth()/2,mx,6);
my=Curve(MouseY()-GraphicsHeight()/2,my,6);
MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2);
camrotation.X=camrotation.X+my/10.0;
camrotation.Y=camrotation.Y-mx/10.0;
RotateEntity(cam,camrotation);
//Player movement
move=KeyDown(KEY_W)-KeyDown(KEY_S);
strafe=KeyDown(KEY_D)-KeyDown(KEY_A);
//Jumping
float jump=0.0;
if (KeyHit(KEY_SPACE)) {
if (!ControllerAirborne(player)) {
jump=4.0;
}
}
//Run
if (KeyDown(KEY_LSHIFT)||KeyDown(KEY_RSHIFT)) {
if (!ControllerAirborne(player)) {
move*=2.0;
strafe*=2.0;
}
}
//Set controller input
UpdateController(player,camrotation.Y,move,strafe,jump);
//Update the world
UpdateWorld();
//Position the camera
TVec3 playerpos=EntityPosition(player);
TVec3 camerapos=EntityPosition(cam);
camerapos.Y=Curve(playerpos.Y+1.75,camerapos.Y,2.0);
camerapos=Vec3(playerpos.X,camerapos.Y,playerpos.Z);
PositionEntity(cam,camerapos);
//Render the scene
SetBuffer(buffer);
RenderWorld();
//Render lighting
SetBuffer(BackBuffer());
RenderLights(buffer);
//Swap the front and back buffer
Flip();
}
exitapp:
return Terminate();
}

I think I am just missing something like SetCollision or SetMass ...

Have you set body mass for the controller?

[MrIslomaniac]

Since that is the complete code, no

Ok that works now =) thank you!

Thought that i can't do that because it requires a TBody ...

Happy

No problems, I never actually looked through your code as the problem is 99.9% of the time not giving the controller mass.

[Elmar]

I have the same problem, but i can't resolve this problem. Can you show me in the code above what you say?

thanks.

[Marleys Ghost]

add:

 

SetBodyMass(player,1);

[Elmar]

But when i add it my controller became very heavy and it began to move off scene. Maybe i do any another mistake?

[Marleys Ghost]

Change:

 

UpdateController(player,camrotation.Y,move,strafe,jump);

 

try:

 

UpdateController(player,camrotation.Y,move*3,strafe*3,jump,500.0f);

[Elmar]

it doesn't work again (

[macklebee]

post your code so someone can see whats happening. without the code they can only guess.

[Marleys Ghost]

post your code.

[Marleys Ghost]

when you say moves off screen do you mean fall ?

[macklebee]

looks like you are loading a gmf and not a sbx file for your scene... you need to create a sbx file in the editor and load that using LoadScene() not LoadModel()... your player doesn't have anything to spawn on perhaps? unless maybe your scene.gmf is an actual scene?

[Elmar]

ok, i will again think about this code...

[Marleys Ghost]

This code works:

 

 

#include "engine.h" 



int main(int argc, char** argv) 
{ 

Initialize(); 

//Create a graphics context 

Graphics(1280,768); 

//Create a world 

if (!CreateWorld()) { 
MessageBoxA(0,"Error","Failed to create world.",0); 
goto exitapp; 
} 


//Create a camera 
TEntity cam=CreateCamera(); 
CameraClearColor(cam,Vec4(0,0,1,1)); 
PositionEntity(cam,Vec3(0,2,-10)); 
Collisions(1,2,true); 

//Load a model 
TModel scene=LoadModel("abstract::scene.gmf"); 
if (scene==0) { 
MessageBoxA(0,"Error","Failed to load model.",0); 
goto exitapp; 
} 

EntityType(scene,2); 
//Create a light 

TLight light=CreatePointLight(); 
PositionEntity(light,Vec3(0,5,0)); 

//Create a render buffer 
TBuffer buffer=CreateBuffer(1280,768,BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL); 

TController player=CreateController(); 
EntityType(player,1); 
SetBodyDamping(player,0.0); 
SetBodyMass(player,1);
SetWorldGravity(Vec3(0,-20,0)); 


float move=0.0; 
float strafe=0.0; 
TVec3 camrotation=Vec3(0); 
float mx=0; 
float my=0; 

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

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

//Camera looking 
mx=Curve(MouseX()-GraphicsWidth()/2,mx,6); 
my=Curve(MouseY()-GraphicsHeight()/2,my,6); 
MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2); 
camrotation.X=camrotation.X+my/10.0; 
camrotation.Y=camrotation.Y-mx/10.0; 
RotateEntity(cam,camrotation); 

//Player movement 
move=KeyDown(KEY_W)-KeyDown(KEY_S); 
strafe=KeyDown(KEY_D)-KeyDown(KEY_A); 

//Jumping 
float jump=0.0; 
if (KeyHit(KEY_SPACE)) { 
if (!ControllerAirborne(player)) { 
jump=4.0; 
} 
} 

//Run 
if (KeyDown(KEY_LSHIFT)||KeyDown(KEY_RSHIFT)) { 
if (!ControllerAirborne(player)) { 
move*=2.0; 
strafe*=2.0; 
} 
} 

//Set controller input 
UpdateController(player,camrotation.Y,move*3,strafe*3,jump,500.0f); 

//Update the world 
UpdateWorld(); 

//Position the camera 
TVec3 playerpos=EntityPosition(player); 
TVec3 camerapos=EntityPosition(cam); 
camerapos.Y=Curve(playerpos.Y+1.75,camerapos.Y,2.0); 
camerapos=Vec3(playerpos.X,camerapos.Y,playerpos.Z); 
PositionEntity(cam,camerapos); 

//Render the scene 
SetBuffer(buffer); 
RenderWorld(); 

//Render lighting 
SetBuffer(BackBuffer()); 
RenderLights(buffer); 

//Swap the front and back buffer 
Flip(); 
} 

exitapp: 
return Terminate(); 
}

Thank you

[Elmar]

when you say moves off screen do you mean fall ?

 

yes

[Marleys Ghost]

yes

 

 

Is this still a problem?

[Elmar]

Is this still a problem?

 

yes(

[Marleys Ghost]

Have you tried moving the start position of the player controller up? are you still using the same .gmf scene?

 

try:

 

PostionEntity(player, Vec3(0.0, 5.0, 0.0));

[Elmar]

Thank you Marleys Ghost, it's working now. How can regulate height of player?

[Marleys Ghost]

regulate?

[Elmar]

to increase or to decrease

[Marleys Ghost]

if you mean the starting height value for the position of the controler then you use PostionEntity as above the Vec3 is three values for that postion Vec3(x,y,z) ... the value for y (5.0 as above) sets the height.
