Is it OK to set __transformDirty on Tile?

Haxe
#1

Will I break something with setting Tile.matrix like this:

matrix.a = 2;
matrix.tx = -10;
__transformDirty = true;

…or should I stick to:

var matrix = new Matrix(2, 0, 0, 1, -10);
this.matrix = matrix;
#2

Does this work?

matrix.a = 2;
matrix.tx = -10;
this.matrix = matrix;
#3

Looks like it does :slight_smile:

Setting a “dirty” flag to true is usually fine, but setting it to false is almost always bad. This is why they’re usually private.

Often, there’s a public way to set the flag to true, and if so, that’s recommended. In this case, it’s matrix = matrix.
