ok so i need some help with limbs.

ive tried looking through the forums and havent found any actual tutorials on how to implement limbs in your program.

so could someone give me some code to practice with (it would really help if you could also explain how the code works)

dont want to double post so i have another question relating to acceleration

i think i have the right code (i found it in another post and edited it a little)

anyway the camera is programmed to point at the object so i can keep track of where the object is. however, when i press the key to trigger the objects movement the camera moves as though the object was moving but the object doesnt move (the camera rotates of into space)

heres the code

for limbs- looka round in the menu and understand how the commands work.
For the sphere. The camera is still pointing to the place the object should be, but you never positioned the object where the camera is pointing. Add a position object command in the loop and there u go

By the way, you are increasing the acceleration with time - this is a bit unusual, normally things work under constant acceleration e.g. gravity or thrust of an engine.

its unrealistic i know but ill work on it later. the only thing im really trying to do right now is make the object start out slow and move faster with time and thats what the code does so im happy

Which is what will happen if you keep the acceleration the same.

In gravity (in the real world) things fall with an acceleration of -9.81m/s2. (- for downwards)

This increases the speed by 9.81 m/s every second - things start out slow and get quicker. Gravity doesn't keep increasing. i think this is a common mistake and is why sometimes computer physics objects fall just a little 'wrong'.

Hope this helps!

yeah i know lol

i just had physics last quarter in school and my teacher really made sure we understood the concepts of motion.

like i said its unrealistic at the moment but ill work to fix that later
