The percentage calculation is just maths.

Код:

% = 100 - (currentValue / maxValue * 100)

//Say maxValue is 60
//At the start: 0% = 100 - (60 / 60 * 100)
//At the middle: 50% = 100 - (30 / 60 * 100)
//At the end: 100% = 100 - (0/ 60 * 100)

When implementing this in pawn, beware of integer division, so use floats.
Implementation method:

• Before the start of the timer, set maxValue.
• Before the start of the timer, set currentValue to maxValue.
• With every tick of the timer, decrease currentValue and update the string if needed.
