Viewport Web

Hi,

how can i change the size of the viewport when i launch my game in firefox?

Thanks in advance,

Hi!

If you talking about size of start window, try to do next - open in text editor YourStartGame.html, and find this

canvas.main:not([fullscreen]) {
  padding-right: 0;
  margin-left: auto;
  margin-right: auto;
  width: 100%;
}

and change width from 100% to 50% or as you need.

and how can i do it in blueprint or is that not possible?

In blueprint you cannot adjust this parameter.
