Cloud Tiles

Cloud tiles are defined like tiles that allow player to move through them from left or right and also jump up, but when player is falling down, he will stand on it.
Im EdurarTe (http://www.youtube.com/user/Edurarte) and im a game developer right now im working with C++
i´ve just made a map format wich lets you specify the type of tile 1 for solid 2 for cloud 3 for special 4 for visible 0 for invisible
but i have never worked with cloud tiles and im just asking for advise on how to manage them.
any advise?

Only check for collision when the y-velocity of the player is downwards.

Welcome to the forum =)
Yeah but he still needs a map format that says "Hey this is a cloud tile only check on positive y-velocity!"
How are you handling maps right now, a grid of numbers with some sort of header? (this seems to be the 'normal' way). If so, you may want to consider changing it so that each tile has it's own line in the map file.
For Example:
Code: Select all
tile # x y w h passage(0 = walkable, 1 = collision, 2 = cloud)
tile 01 00 00 32 32 1
tile 02 32 00 32 32 0
tile 03 64 00 32 32 2
tile 04 96 00 32 32 2
Obviously there are plenty of other ways you could handle this. I had a very hard time finding any information about how other people did it, so I made up my own method where I have a data file which goes something like:
Code: Select all
tileset #oftiles
tile# [bunch of irrelevant animation data] passage
[More tiles..]
Example (Map1.dat):
Code: Select all
images\tileset.png 6
00 [animation junk] 0 //grass
01 [animation junk] 0 //dirt
02 [animation junk] 1 //stone
03 [animation junk] 0 //carpet
04 [animation junk] 1 //wall
05 [animation junk] 1 //door
Then in my map file (Map1.map):
Code: Select all
data\Map1.dat
640 480 1 16 16
01 01 01 01 01 01 01 01 01 01
01 02 02 01 01 03 03 03 01 01
01 02 02 01 01 03 01 01 01 01
01 01 01 01 01 03 01 01 01 01
01 03 03 03 03 03 02 02 02 02
01 01 01 01 01 01 02 02 02 02
Which follows the format:
Code: Select all
datafile
width height layers tilewidth tileheight
[Tile data as grid]
As I pointed out, there are many different ways to do this, and you'll probably end up adopting from a few and customizing them for your needs. Hope I didn't confuse you too much.

Thanks all you guys, the thing about cloud tiles i tried to do that but didnt work so i found out the answer in a spanish SDL website about SDL game programming called LosersJuegos, and the way i did this is by changing the way my collsion works,
to a way that finds out how many distance are from the floor to my player and returns the value, which im still implementing it
also i was talking about that i have made a map format no that i needed one, but thanks dandymcgee, this is how my map format look like
Code: Select all
[size] 10 16 // width and height
[tileset] iceset.bmp

the first two lines are read first to make a vector of that size (Wich was very complicated in C++) and the tileset and background specifies the image file,
the matrix looks like
numberOfTile typeOfTyle(0 invisible, 1solid, 2 cloud, 3 special, 4 visible)
and there are two layers bottomlayer and fromlayer
And damn it works great! i just needed the cloud collision manager,
but thanks to all you guys 
I look forward for you visit my channel, a video of the game will be uploaded as soon as i finish it,

since you guys are talking about this anyways, i have been wanting to make my own map format reading thingy... i am going to make a small dungeon RPG in the console.
how would i go about doing this, i want something like...
Code: Select all
1 0 1 1 1 1 1 1 1 1
1 0 0 0 0 1 0 0 0 0
1 0 0 1 0 1 0 0 0 1
1 0 0 0 0 1 0 0 0 1
1 0 0 0 0 0 0 0 0 1
1 0 0 0 0 1 1 1 1 1
1 0 0 1 1 1 0 0 0 0
1 1 0 1 0 0 0 0 0 0
and that would come out like
â–“â–‘â–“â–“â–“â–“â–“â–“â–“â–“
â–“â–‘â–‘â–‘â–‘â–“â–‘â–‘â–‘â–‘
â–“â–‘â–‘â–“â–‘â–“â–‘â–‘â–‘â–“
â–“â–‘â–‘â–‘â–‘â–“â–‘â–‘â–‘â–“
â–“â–‘â–‘â–‘â–‘â–‘â–‘â–‘â–‘â–“
â–“â–‘â–‘â–‘â–‘â–“â–“â–“â–“â–“
â–“â–‘â–‘â–“â–“â–“â–‘â–‘â–‘â–‘
â–“â–“â–‘â–“â–‘â–‘â–‘â–‘â–‘â–‘
or something along those lines
if anybody would like to tell Josh how Josh can go about loading things like this ( mostly need help with printing out all of it)
i can handle character movement, collision etc. etc. this is what i need help with right now
isn't there some sort of
for or
while loop i need er one inside of one er something

One way to do it would to do this:
Code: Select all
10
1 0 1 0 0 0 1 1 0 1
1 0 1 1 1 1 1 1 0 1
1 0 0 0 0 0 0 0 0 1
1 1 1 1 1 1 1 1 1 1
The first line in the file is the # of numbers per row.
bool loader() :
Code: Select all
ifstream myMap("mymapfile.txt");
int lineLength;
int curNum;
if (!myMap)
return false;
myMap >> lineLength;
while (myMap) {
for (int i = 0;i < lineLength;++i) {
myMap >> curNum;
if (curNum == 1)
cout << "â–“";
else
cout << "â–‘";
}
cout << endl;
}
return true;
This will assume that your map file is formatted correctly. You can use a stringstream and get one line of the file at a time to check that it's not formatted correctly. ("myMap >>" regards all whitespace as equal so \n is the same as " " so you'd have to get a line at a time in order to test for \n)

Outputting data would be something like:
Code: Select all
for( int y = 0; y < tileColumn; y++ )
{
for( int x = 0; x < tileRow; x++ )
{
mapStreamOut << mapData[x][y] << " ";
}
mapStreamOut << std::endl;
}
Input would be very similar:
Code: Select all
for( int y = 0; y < tileColumn; y++ )
{
for( int x = 0; x < tileRow; x++ )
{
mapStreamIn >> mapData[x][y];
}
}
tileColumn and tileRow are just ints that store the number of tiles in each column/row.
EDIT: Marauder beat me to it.

not great...
still doesn't completely work, because when i load Labyrinth.txt
it takes the far most left column and puts it on the
RIGHT instead... can anybody tell me how to fix whatever the problem might be?
(e.g)
Code: Select all
10
1 1 1 1 1 1 1 1 1 1
1 0 0 0 0 0 0 0 0 1
1 0 0 0 0 0 0 0 0 1
1 1 1 1 1 1 1 1 1 1
is labyrinth,
output of console
Code: Select all
#include <iostream>
#include <fstream>
#include "timer.h"
using namespace std;
int level = 1;
int load(){
ifstream mapfile("maps/Labyrinth.txt");
int ylen;
int xlen;
int tile;
if(!mapfile)
cout << "Could not load the level\n"
<< "The files could be corrupt, please replace them to continue\n";
mapfile >> ylen;
mapfile >> xlen;
while(mapfile)
{
for(int i = 0; i < ylen; i++)
{
for(int j = 0; j < xlen; j++)
{
mapfile >> tile;
if (tile == 1)
cout << "X";
if (tile == 2)
cout << "^";
if (tile == 0)
cout << " ";
}
}
cout << endl;
}
cout << "W-up A-left S-down D-right\n";
return true;
};
int main(){
while (level){
load();
wait(1);
system("cls");
}
return false;
}

thank you VERY MUCH!!! lol haha serisouly thanks... although it would have been preffered that you left timer.h and wait(1); lol because I<- DO have a timer... here it is incase any one cares
Code: Select all
#include <iostream>
#include <time.h>
void wait ( int seconds )
{
clock_t endwait;
endwait = clock () + seconds * CLOCKS_PER_SEC ;
while (clock() < endwait) {}

I could've put it back in, but I did actually run test this so I needed something that I could compile.
