A cheap way of doing it, would be to create your algae model or whatever, then continuously scale it in the loop by a scale factor, first if it is algae, you may want it to spread out first, before taking hight, so you might scale it by the x and y axisis, then once those reach a certain limit, you start to scale it's y axis, so that it grows taller. Of course, that is not exactly Dynamic, if that is what you are looking for, but it is certainly a way to make an abject appear to grow. Here is an example
do
if scalefactorx(0)<100
scalefactorx(0)=scalefactorx(0)+1
endif
if scalefactoryz(0)<100
scalefacorz(0)=scalefactorz(0)+1
endif
if scalefactorx(0)=100 and scale factory(0)=100
if scalefactory(0)<100
scalefactory(0)=scalefactory(0)+1
endif
endif
scale object 1,scalefactorx(0),scalefacory(0),scalefactorz(0)
loop
to make the object die, you would wait untill the y scale factor reached it's maximum, then youw ould start to decrease the different scale factor variables.
Guns arn't the problem, people are the problem, shoot all the people and guns arn't a problem anymore.
