I've been trying to extract a float value from some custom tweens added to a tweenchain using GetTweenCustomFloat1, GetTweenCustomFloat2 etc with no luck.
I can fake the desired behaviour using tween sprites but are custom tweens working in tween chains?

Problem 2: CreateTweenCustom doesn't work if its duration is set to 0. SetTweenDuration later in the code does nothing; minor but annoying to track down.
SetWindowSize( 800, 480, 0 )
SetVirtualResolution( 800, 480 )
my_tween = CreateTweenCustom(0) //custom tween doesn't work if initialised to 0. change it to 0.1 and it does work
SetTweenCustomInteger1(my_tween,0,1000,0)
do
// press left mouse button or tap screen to start
if GetPointerPressed() = 1
setTweenDuration(my_tween, 5.0)
PlayTweenCustom(my_tween,0.0)
endif
// get the tween value
tween_value = GetTweenCustomInteger1(my_tween)
print(tween_value)
UpdateAllTweens( getframetime() )
