The following paragraphs describe the above script on a line by line basis.
IF burner AND alt > 400.0 THEN
burner = FALSE
ENDIF
If the fuel burner is on, based on Boolean point 'burner' set to 'TRUE', and the
altitude of the balloon, based on point 'alt', exceeds 400, then the fuel burner is
turned off. Point 'alt' is measured in pixels between 140 and 1000, so the
value of 400 is the height in pixels.
IF burner THEN
fuel = fuel - rate
IF fuel < 0.0 THEN
fuel = 0.0
burner = FALSE
ENDIF
ENDIF
If the fuel burner is on, the amount of fuel remaining decreases by the rate of
ascent. The rate of ascent, point 'rate' can be modified by moving the slider. If
point 'fuel' currently has a value of less than 0, then there is no fuel left and the
fuel burner is turned off.
IF burner AND fuel > 0.0 AND rate > 0.0 THEN
lift = lift + rate/5.0
