R123 - Tween Behavior - When using "Elastic" easing the value goes to "NaN" if target value and start value are equal #2201

Closed Fib100 closed 5 years ago

Fib100 commented 5 years ago

Problem description

When tweening any value (this includes all tweenable properties) and using "Elastic" as the easing (in, out, and in-out) and the target value is equal to the end value, the value goes to "NaN".

In my example I'm using the value tween. But I've also tested it with the other properties such as X, Y, Width, Height, and Angle and have observed the same result. The core issue seems to lie with the Elastic easing option.

Attach a .c3p

tween_elastic_easing_bug.c3p

Steps to reproduce

  1. Download the c3p file then load it in Construct 3 R123
  2. Run the project
  3. Observe the text object showing "NaN" as the value

Observed result

The value of the property goes to "NaN".

Expected result

If the start value and the target value are equal, then the value should remain the same (ex: start = 100, target = 100, then the result should remain at 100)
