Thread: SDL Events in seperated.

Hello Folks,

I try to make a little game Pong. Now i have a situation: i have 4 keys defined;

for player 1: keys w and s. w = UP, S = DOWN.
for player 2: Keys down arrow, up arrow.

the problem is that i want the bats of the player keep moving if the player hold their the down/up keys. but it quickly turned out that if both players hold or push their up/down keys only one of them can move (because my SDL_Event Object can only hold one of the pushed keys)

So i wondered if their is a way to make 2 separated SDL_Event Objects that only handles specific keys of the player so:

SDL_Event EventsPlayer1 handles s and w keys.
SDL_Event EventsPlayer2 handles UP and DOWN arrow keys.

So is their a way to handle multiple keys with SDL?

EDIT:

I already tried the SDL function SDL_EnableKeyRepeat(int delay, int interval), but this solves only a part of the problem. it can repeat a key correctly but, it cant manage multiple keys at the time).

Thanks for helping!

Jelte.

if somebody is curious about how i tried to handle this problem, check this code:

Code:

					while(SDL_PollEvent(&Event))
        			{
           					if(Event.type == SDL_QUIT)
            				{
                				Quit = true;
            				}
            				else if(Event.type == SDL_KEYDOWN)
            				{
                				if(Event.key.keysym.sym == SDLK_ESCAPE)
                				{
                    					Quit = true;
                				}
								else if(Event.key.keysym.sym == SDLK_w || Event.key.keysym.sym == SDLK_UP || 											Player1HoldKeys == true || Player2HoldKeys == true)
								{
									if(Event.key.keysym.sym == SDLK_w || (Player1HoldKeys == true &&
									   this->LastKeyPressed == 2))
									{
										this->Player1HoldKeys = true;
										this->LastKeyPressed = 2;
										this->ObjPlayer1->MoveBat(true,this->ObjGraphics->ReturnWindowHeigth());
									}
									else if(Event.key.keysym.sym == SDLK_UP || (Player2HoldKeys == true && 
									   this->LastKeyPressed == 4))
									{
										this->Player2HoldKeys = true;
										this->LastKeyPressed = 4;
										this->ObjPlayer2->MoveBat(true,this->ObjGraphics->ReturnWindowHeigth());
									}
            					}
								else if(Event.key.keysym.sym == SDLK_s || Event.key.keysym.sym == SDLK_DOWN ||
										Player1HoldKeys == true || Player2HoldKeys == true)
								{
									if(Event.key.keysym.sym == SDLK_s || (Player1HoldKeys == true && 
									this->LastKeyPressed == 1))
									{
										this->Player1HoldKeys = true;
										this->LastKeyPressed = 1;
										this->ObjPlayer1->MoveBat(false,this->ObjGraphics->ReturnWindowHeigth());
									}
									else if(Event.key.keysym.sym == SDLK_DOWN || (Player2HoldKeys == true && 
									   this->LastKeyPressed == 3))
									{
										this->Player2HoldKeys = true;
										this->LastKeyPressed = 3;
										this->ObjPlayer2->MoveBat(false,this->ObjGraphics->ReturnWindowHeigth());
									}
								}
							}
							else if(Event.type == SDL_KEYUP)
							{
								if(this->LastKeyPressed == 1 || this->LastKeyPressed == 2)
								{
									this->Player1HoldKeys = false;
								}
								else if(this->LastKeyPressed == 3 || this->LastKeyPressed == 4)
								{
									this->Player2HoldKeys = false;
								}
								this->LastKeyPressed = 0;
							}
         			}
					this->ObjGraphics->MoveBall();	
					this->ObjGraphics->Draw(this->ObjPlayer1,this->ObjPlayer2);

You can use SDL_KEYUP to keep track of when a key is released. For example, if you get a SDL_KEYDOWN event, you can assume that the key is held down until a corresponding SDL_KEYUP event happens.
