Newbs need help with collision detection.

[Duhjoker]

ok I tried to add the code above and im having a few problems first no class member for solid I assume means its not in my library. and well.....

Code: Select all

It's there in the thread I linked you to Summoner123 tells you what code to add to your library, although I had problems getting it to work

[Duhjoker]

Ahhh man are you kidding me? I have to mess around with a .cpp file? Did you get it to work?

[Duhjoker]

installing visual studio express now, may take a minute. Do I just write that starting at line 735 then save it or do I try to compile it?

[naed]

I tried to just write it to the file using notepad+ but it gave me a permission error when compiling the gamebuino code

[Duhjoker]

Yea I've tried that before too. I ended up having to leave my laptop on all night so VSE could finish installing. I am able to open the file now but still not sure where to put the extra lines of code.

[naed]

I'm sure Sumoner123 states what line the code needs to be inputted into

[Duhjoker]

OK I sent a private messgage to summoner123 and he was nice enough to shrare a his display.h and .cpp with us. these two files will give us....

gb.display.numcollision

gb.display.solid[index].x

gb.display.solid[index].y

gb.display.solid[index].sprite col

you can find them here at my dropbox

https://www.dropbox.com/sh/89kqtgi27sf1 ... 2SVRa?dl=0

I also have a link to 4shared if you need it here....

http://www.4shared.com/rar/qVqkpLkQce/d ... er123.html

he says to make copies of the current display.h and .cpp and drag and drop his versions back to the library folder.

Thank you so much summoner123


You can test with this

Code: Select all



//this code will check if a character is touching in any tile on the screen

for(i=0; i < gb.display.numcolision + 1; i++)  //Range  "i" to number of tiles rendered

   {

 if(gb.collideRectRect(player.posX,player.posY,8,8,gb.display.solid[i].x,gb.display.solid[i].y,8,8))
    {
   
         //here - Colision is true

          if(gb.display.solid[i].spritecol == pointer )
             {
              //  sprite has collided with your character = Pointer
              }

      }   
  } 


[naed]

Oh wow! That's awesome ☺

Looks like I'm playing with this tonight then, I'll post my results
