Why are custom fonts slowing down my program?
So I’m making a project in p5.js which aim to reproduce the Matrix rain code effect.
It ran pretty smooth until I decided to load a custom font.
When I did, my framerate dropped considerably. And it’s the case for every custom font that I try to load (only when I use the loadFont function; if I use textFont and some default font it doesn’t seem to slow down)
Of course, I use the loadFont function in the preload function, and textFont in setup, so I don’t know if this is a known thing ? How could I avoid this ?
Here is a Minimum Viable Example of the problem :
var characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789$+-*/÷=%"'#&_(),.;:?!\|{}<>^~ "
var font;
var spacing_width = 10;
var spacing_height = 20;
function preload() {
font = loadFont('matrix_font.otf');
}
function setup() {
createCanvas(window.innerWidth, window.innerHeight);
frameRate(60);
background(0);
textFont(font);
fill(255)
}
var lastUpdate;
function draw()
{
background(0);
var timeSinceLastUpdate = new Date().getTime() - lastUpdate;
print(timeSinceLastUpdate + "ms") // prints time elapsed between each frame
lastUpdate = new Date().getTime();
for(var i = 0; i < 40; i++)
for(var j = 0; j < 40; j++)
text(characters[int(random(0, characters.length))], j * spacing_width, i * spacing_height)
}
This code prints in the console values around 40-50ms, but when I comment out the line textFont(font); the values are around 10-20ms
I'm using this font but I have the problem with every font that I try to load
