Taper Door (minimalistic)

Example prim settings for these types of doors:

• Type: Box
• Size: <2.5, 3.75, 0.01>
• Rotation: <270, 0, 0>
• Hollow: 0.90
• Taper-x: -1
• Taper-y: 0

//to alter script, see touch start,
//first value is magnitude (how much to change by, larger is 'faster')
//second value is rate of change (smaller is faster)
//Example DecreaseTaper(0.01, 0.02)
//0.01 = change by 0.01,
//0.02 = pause for 20ms between each change

//time to keep door open defined here:
float openpause = 2.0; //2.0 = 2 seconds

// Area not to touch starts here (scroll down to make changes)
