2 buttons pressed = 0

Hi, I have set up the condition so that when I press (in this case (down + (left or right)) && (up && (left or right)) that all LINEAR movement is canceld. IMPORTANT: my player only travels X or Y, no diagnols. I set up the correct if statments and it works however I have 2 questions from it.


When both buttons are pressed at the same time [italics](or as in most cases)[/italics] nano seconds apart due to human error, my player appears to make a slight diagonal jump before stopping. So my question is, is there any way to create a "buffer" between button presses so that this does not occur & is there a simpler way to code what I have coded.

Thanks,
Ren

function Spacer3000Controls::onUpdate(%this)
{
	%this.owner.setLinearVelocityY((%this.down - %this.up) * %this.YSpeed);
	%this.owner.setLinearVelocityX((%this.right - %this.left) * %this.XSpeed);
	
	if(%this.up && %this.left) 
	{
		%this.up = 0;
		%this.left = 0;	 
	}
	if(%this.up && %this.right)
	{
		%this.up = 0;
		%this.right = 0;
	}
	if(%this.down && %this.right)
	{
		%this.down = 0;
		%this.right = 0;
	}
	if(%this.down && %this.left)
	{
		%this.down = 0;
		%this.left = 0;
	}
}
