C++ (Cpp) Vector2D::SingleAxis Examples

Example #1

File: visual_tool_scale.cpp Project: Gpower2/Aegisub

void VisualToolScale::UpdateHold() {
	Vector2D delta = (mouse_pos - drag_start) * Vector2D(1, -1);
	if (shift_down)
		delta = delta.SingleAxis();

	scale = Vector2D(0, 0).Max(delta * 1.25f + initial_scale);
	if (ctrl_down)
		scale = scale.Round(25.f);

	SetSelectedOverride("\\fscx", wxString::Format("%d", (int)scale.X()));
	SetSelectedOverride("\\fscy", wxString::Format("%d", (int)scale.Y()));
}

Example #2
