Lite-c key pressed question #255106 03/07/09 16:34 03/07/09 16:34

Here is the code: if(key_space == 1) { my.z += 10; } My question is, is there is a way so that when you press the space key once, it will run my.z += 10 just once, and not keep running. So basically you press the space key, and it only runs the code once and then you have to release the space key and hit it again for it to run the code again. Thanks!

IE: Code: function main() { ... on_space=player_jump; //call this just once ... } function player_jump() { player_entity.z += 10; //ME is not valid here } or a messier way (but still acceptble) would be Code: action your_action() { var space_pressed = 0; //before WHILE loop starts ... if(key_space==0) { space_pressed = 0; } else { space_pressed = 1; if(space_pressed==0) my.z += 10; } ... } "There is no fate but what WE make." - CEO Cyberdyne Systems Corp.

Here you go:

Code:

action player_move
{
	player= me;
	wait(1);
	camera.genius = player;
	shift_sense= 2;
	
	
	while(player!=NULL)
	{
		//Walking function arrow keys
		move_vec[0]= (key_cuu - key_cud)*8*time;
		move_vec[1]= (key_comma - key_period)*6*time;
		
		//Stair Climbing and falling
		vec_set(temp,my.x);
   	temp.z -= 4000;
   	trace_mode = ignore_me+ignore_sprites+IGNORE_MODELS+USE_BOX;
   	move_vec.z=(-trace(my.x,temp))*3*time;
	   player.pan -= (key_force.x)*1.5*time;
	   move_mode = IGNORE_YOU + IGNORE_PASSABLE + IGNORE_PUSH + ACTIVATE_TRIGGER + GLIDE;
  	   ent_move(move_vec,NULLVECTOR);
  	   
  	   //jumping
	
		
		//Running with arrow keys
		if(key_shift == 1)
		{
			move_vec[0]= (key_cuu - key_cud)*4*time;
		}
		player.pan += (key_cul - key_cur)*2*time;
		ent_move(move_vec,NULLVECTOR);
		if(move_vec[0]== 0 && move_vec[1]==0)
		{
			//Idle
		idle_percent= (idle_percent +5*time)%100;
		ent_animate(me,"stand",idle_percent,ANM_CYCLE);
	}
	else
	{
		//Running animation
		if(key_shift)
		{
			run_percent = (run_percent + sign(move_vec[0])*5*time)%100; 
			ent_animate(player,"run",run_percent,ANM_CYCLE); 
		}
		else
		{
		//Walking animation
		walk_percent = (walk_percent+ sign(move_vec[0])*5*time)%100;
		ent_animate(player,"walk",walk_percent,ANM_CYCLE);
	   }
   }
   

	   //The Camera
		vec_set(Camera.x,player.x);
		camera.z += 39;
		camera.pan = player.pan;
		temptilt += (key_pgup - key_pgdn)*4*time;
	   if(key_home){ temptilt =0;}
		if (temptilt > 75)
		{
			temptilt = 75;
			
		}
		else
		{
			if(temptilt < -75)
			{
				temptilt= -75;
			}
		}
		camera.tilt =0 +temptilt;
		wait(1);
	}
}

I cant see anywhere in the code mentioning trying to use the space key,
so I'll guess its the apparently blank junping section.

Code:

action player_move
{
	player= me;
	wait(1);
	camera.genius = player;
	shift_sense= 2;
	var space_held = 0;         //<<Added
	
	while(player!=NULL)
	{
		//Walking function arrow keys
		move_vec[0]= (key_cuu - key_cud)*8*time;
		move_vec[1]= (key_comma - key_period)*6*time;
		
		//Stair Climbing and falling
		vec_set(temp,my.x);
   	temp.z -= 4000;
   	trace_mode = ignore_me+ignore_sprites+IGNORE_MODELS+USE_BOX;
   	move_vec.z=(-trace(my.x,temp))*3*time;
	   player.pan -= (key_force.x)*1.5*time;
	   move_mode = IGNORE_YOU + IGNORE_PASSABLE + IGNORE_PUSH + ACTIVATE_TRIGGER + GLIDE;
  	   ent_move(move_vec,NULLVECTOR);

  	   
		//jumping
		if(key_space==0)    
			space_pressed = 0;
		else    
		{
			space_pressed = 1;
			if(space_pressed==0)   player.z += 10;
		}
	
		
		//Running with arrow keys
		if(key_shift == 1)
		{
			move_vec[0]= (key_cuu - key_cud)*4*time;
		}
		player.pan += (key_cul - key_cur)*2*time;
		ent_move(move_vec,NULLVECTOR);
		if(move_vec[0]== 0 && move_vec[1]==0)
		{
			//Idle
		idle_percent= (idle_percent +5*time)%100;
		ent_animate(me,"stand",idle_percent,ANM_CYCLE);
	}
	else
	{
		//Running animation
		if(key_shift)
		{
			run_percent = (run_percent + sign(move_vec[0])*5*time)%100; 
			ent_animate(player,"run",run_percent,ANM_CYCLE); 
		}
		else
		{
		//Walking animation
		walk_percent = (walk_percent+ sign(move_vec[0])*5*time)%100;
		ent_animate(player,"walk",walk_percent,ANM_CYCLE);
	   }
   }
   

	   //The Camera
		vec_set(Camera.x,player.x);
		camera.z += 39;
		camera.pan = player.pan;
		temptilt += (key_pgup - key_pgdn)*4*time;
	   if(key_home){ temptilt =0;}
		if (temptilt > 75)
		{
			temptilt = 75;
			
		}
		else
		{
			if(temptilt < -75)
			{
				temptilt= -75;
			}
		}
		camera.tilt =0 +temptilt;
		wait(1);
	}
}

The problem is this section: Code: space_pressed = 1; if(space_pressed==0) player.z += 10; First you set space_pressed to 1 and then check if its 0. But at that point it'll never be 0 because you set it to 1 first. Try replacing the whole jumping part with: Code: if(key_space} { space_pressed = 1; } else { if(space_pressed) { space_pressed = 0; my.z += 10; } }

Code:

#define k_space 57
//define k_space = 57;
var k_nSt[50];
var in_n1 = 0;
var in_n2 = 0;

function kf2(var _nScanCode) {
	in_n1 = key_pressed(_nScanCode);
	in_n2 = in_n1 && !k_nSt[_nScanCode];
	k_nSt[_nScanCode] = in_n1;
	return(in_n2);
}
// usage:
if (kf2(k_space)) {

}
