I managed to get the code working, but only in room script, not in global script. ive tested it with a display command on the is timer expired and it works! but still the GUI wont update even i put the codes at repeatedly execute always on the global script.
quick reply and hopefully correct
thank you there Slasher!
I've tried the code, ran without error, but the text in GUI are not changed somehow after 15 seconds.
I've also tried to moveCode: Adventure Game Studio
from the globalscript.ash to the globalscript.asc but it gave me errorCode: Adventure Game Studio
I suppose i will have to set the condition in the same code brackets as above?
SnarkyThe key element of the pancake model is that when floors from above crash into the lower ones, they'll push them down (so the lower floors won't just start free-falling from a rest state).
Depends on how much energy is consumed at each step. If nearly all energy is lost with just enough to trigger the next floor, then the next floor would start from rest.
We can do this for every floor, or every 10 floors (thus different arrangements of billiard balls) which is synonymous with modelling the different scenarios of energy losses.
The 9/11 commission report itself said the collapse took 10 seconds. Any other value in the vicinity of 10 seconds is at the lower end of the range of values. If you argue 100 seconds is a ridiculous time, then wouldn't it be fair to say 10 seconds is equally ridiculous? Nevertheless, this is what we see.
Billiard ball example
The billiard ball example is simply using billiard balls as timing devices, each starting at rest and then accelerating at free fall when triggered, like a relay race. Billiard balls are not interacting in this example; they are just timing devices. It is interesting to note that one billiard ball dropped from the top of the building takes about 10 seconds to hit the ground at free fall. Additional billiard balls are introduced to incorporate a resistance or hauling effect in the progression. Different arrangements of billiard balls are used to show different scenarios. The example serves to illustrate that the overall collapse (assuming it is possible) should have taken longer than 10 seconds. The example should not be confused with attempting to calculate an actual collapse time.
1. The buildings fell too quicklyQuoteObviously a progressively increasing number of floors have more mass than an single floor. So as the collapse proceeds, the falling mass's velocity loss is proportionally smaller and smaller.
This is incorrect. Conservation of momentum says that as two masses impact and combine (inelastic collision), then the resulting velocity decreases. This means the collapse could not have been faster than free fall speed.
My argument is that resistance in the progression (assuming there's enough energy to keep it going) should slow things down and produce an overall collapse time somewhere between 10 and 100 seconds depending on how much energy is lost along the way.
The towers did indeed fall near free fall speed. Does this make sense?
The demolition expert you mention, Brent Blanchard, focusses on the implausibility of a controlled demolition by conventional means (e.g. dynamite). This is fine, but he instead supports the progressive gravity-driven collapse model and does not question the implausibility of this. In reality, under the gravity-driven "pancake" model, there wouldn't be enough energy to pulverise floors and also keep the collapse going. *
