Need help with tile engine collisions
Posted: Sat Apr 18, 2009 10:41 pm
Can somebody tell me how to add collisions between my player and my layer?
My Code works something like this -
And for my player, I just have it display on the screen like so
So how do I make it so that if the player hits the wall (index 1) he stops?
my update is roughly like this
My Code works something like this -
Code: Select all
render()
{
for (int r = 0; r < rows; r++)
{
for (int c = 0; c < columns; c++)
{
switch(myLayer.get_tile(r, c))
{
SDL_Rect rect;
rect.x = c;
rect.y = r;
rect.w = 50;
rect.h = 50;
case 0:
break;
case 1:
SDL_BlitSurface(tileImage, NULL, screen, &rect);
break;
}
}
}
}
Code: Select all
SDL_Rect rect;
rect.x = myPlayer.get_x();
rect.y = myPlayer.get_y();
rect.w = 50;
rect.h = 50;
SDL_BlitSurface(playerImage, NULL, screen, &rect);
my update is roughly like this
Code: Select all
if (RIGHT)
myPlayer.add_x(1);
if (LEFT)
myPlayer.add_x(-1);
but now it supports collisions and many other things.
