QUESTION
I created simple tilemap using Tiled (3200 x 3200 pixels). I loaded it on my canvas using this library
I draw entire tilemap 3200 x 3200 60 times per seocnd. I tried to move around and it works fine. Btw, I move around canvas using ctx.translate. I included this in my own function
But when I created bigger map in Tiled ( 32000 x 32000 pixels ) - I got a very freezing page. I couldn't move around fast, I think there was about 10 fps
So how to fix it? I have to call drawTiles() function 60 times per second. But is there any way to draw only visible part of the tile? Like draw only what I see on my screen (0, 0, monitorWidth, monitorHeight I guess)
Thank you

Answered 2019-May-14 at 19:55If you have a large tile set and only see part of it in the canvas you just need to calculate the tile at the top left of the canvas and the number of tiles across and down that will fit the canvas.
Then draw the square array of tiles that fit the canvas.
In the example the tile set is 1024 by 1024 tiles (worldTileCount = 1024
), each tile is 64 by 64 pixels tileSize = 64
, making the total playfield 65536 pixels square
The position of the top left tile is set by the variables worldX
, worldY
