Simply Maya User Community - View Single Post - Expression invalid after edit

I don't think "Total_LengthShape.distance.time" exists and also lines like...

else if (Total_LengthShape.distance > 200) && (Total_LengthShape.distance.time -1 <= Total_LengthShape.distance.time))

cause syntax issues because of missing parentheses, it should be...

else if ((Total_LengthShape.distance > 200) && (Total_LengthShape.distance.time -1 <= Total_LengthShape.distance.time))

I don't quite know what you're after but if the middle sphere should only be moving in the Y axis then why include the Z axis in the expression at all? I opened the scene and commented out the lines concerning the Z axis and the center sphere went up and down as the two end spheres moved back and forth.

i think you are right, that the .time i use is not possible
i tried using that cause in my opinion that is what is needed to get it working properly
i could be completely wrong ofcourse

since this is my first expression, i do the best i can, but it seems my knowledge of expressions is not sufficiant to create what i intend.....

the idea of the .time, was to let the expression check the previous distance and the current distance, and then use a < or > formula to let it know the spheres are moving towards each other or away from each other and change the movement in Y accordingly

so the output would be more accurate to the animation and aim of what i try to create

the Z axe is in the equasion because the centre sphere has to be in the exact centre between the 2 outer spheres

herewith my latest file and a little video to explain where my goal lies

thank you for your time
hoping we can solve this here at the forum......
