Material and function to adjust the effect:

//Shaking of the Screen
MATERIAL* ScreenShaking_mat =
{
	effect = "shake.fx";
}

function ScreenShaking_set_Value(Speed,Amplitude)
{
	ScreenShaking_mat.skill1 = floatv(Speed);	// should be around 1
	ScreenShaking_mat.skill2 = floatv(Amplitude);	// this shouldn´t be higher than 0.1
