TileGridSystem

Rxvlism

Can anyone help me recreate this or understand this for loop? I also don’t get the i++ or j++ ( means increase by one so I’m guessing i += 1 ?).

// Resource 

Var blockSize = sprite_get_width*h ( oDirt );

For ( var i = 0; i < room_width / blockSize; I++ ){//Colums
    var xx = i * blockSize;
    For ( var j = 0; j < room_height / blockSize; j++ ){//Rows
        var yy = room_height - blockSize - j*blockSize;
        Instance_create ( xx, yy, oDirt );
    }
}

All the program is doing is printing a tile on a grid = to Width & Height of the screen.

The FUZE version of the C loop would be:

for i = 0 to room_width loop
   // do stuff
repeat

But I mean what’s ; is that to, or, +, - ?? And what about I++

Dave

@Rxvlism Your first semi colon is indeed the "to", and rather than using I++ as the increment, you define a step. So, for example:

for (int i = 0; i < 10; i += 2){
    // things
}

Becomes:

for i = 0 to 10 step 2 loop
    // things
repeat

To count backwards:

for i = 10 to 0 loop
    // things
repeat

Or, with a step:

for i = 10 to 0 step -2 loop
     // things
repeat

When incrementing upward, For loops count up to but not including the last value. When counting downward, they count down to and including the last value.

What about instance create ? Just a setSpriteLocation

Dave

@Rxvlism I'm not quite sure I understand what you're asking here! Could you elaborate?

Rxvlism

Instance_create ( xx, yy, oDirt );
What would this look like in Fuze ?
GetSpriteImage
DrawSprite or Image

I’m confused at how to call oDirt at xx and yy

Dave

Probably better to avoid using the sprite commands for the drawing of a map or background, they're intended for characters/objects/animation and make it very easy to interact with a map drawn in the Map Editor loaded with loadMap(). Depending on whether this dirt tile is from a tilesheet or is an image unto itself, you'll probably have more success with drawImage() or drawSheet(). For example:

// load tilesheet - let's say the dirt tile is tile no. 3
sheet = loadImage("filename")

// using the tileSize function gives us a vector for the tile dimensions
tSize = tileSize( sheet, 3 )
scale = 2

for y = 0 to gheight() step tSize.y * scale loop
    for x = 0 to gwidth() step tSize.x * scale loop
        drawSheet( sheet, 3, x, y, scale )
    repeat
repeat

This gives me something like what you're describing!

Im using my own image 16x16 pixels and when I use tileSize I get the “this image does not have tile data.” I don’t use tile sheets for this reason or I’d make one big png

Nisse5

@Rxvlism If you just use one single tile in the image, you can use drawImage()

Rxvlism

Finally :D you guys are the best For Loops had me going nuts for a bit there!

Thanks @Dave & @Nisse5

Dave

Yep - so it would look something like this:

// load tilesheet - let's say the dirt tile is tile no. 3
img = loadImage("filename")
 
// using the tileSize function gives us a vector for the tile dimensions
tSize = imageSize( sheet )
scale = 2
 
for y = 0 to gheight() step tSize.y * scale loop
    for x = 0 to gwidth() step tSize.x * scale loop
        drawImage( sheet, x, y, scale )
    repeat
repeat

Just in case anyone else was wondering how it looks with drawSheet.

Rxvlism

Is there a getPerlinNosie function in Fuze or will I have to create it ?

pianofire

@Rxvlism You could always ask this person nicely!

Rxvlism

@pianofire

That’s exactly what I’m looking for but 2D how would I contact them the forums ?

pianofire

@Rxvlism Not sure if they are on here but this person has the same avatar https://fuzearena.com/forum/user/minatsu

Pretty sure that is the user on twitter. みなつ reads Minatsu in English!

Ok I msg him/her thanks guys so much !!! <3
