I am using curvevalue to interpolate smoothly positions data on my multiplayer game, now I am trying to smooth also the rotation using curveangle but it has weird behavior, look at the code below:

The problem is that the curveangle command was intended for use with floats, and so what you see here is a side effect of dropping the decimal digits when casting from float to integer. Similarly to the curvevalue command, it seems the equation used by curveangle is somewhere along the lines of:

resultangle = currentangle + ( ( destinationangle - currentangle ) / speedvalue )

When rotating from 300 to 100, curveangle attempts to take the shortest path by increasing the angle with the intent of wrapping back around to complete the transition (300->359->0->100). Because your speed value is set to 100, when the current angle = 0 the result returned by curveangle is 1 because:

resultangle = 0+( (100-0) /100) = 0+(100/100) = 0+1 = 1

However during the next iteration (where currentangle=1), the calculation becomes:

resultangle = 1+( (100-1) /100) = 1+(99/100) = 1+0.99 = 1.99

Now when attempting to store the floating-point value of 1.99 within an Integer, everything after the decimal point is dropped and becomes a value of 1.

even trying with decimals (300.111 and 100.111) I have the same problem

Edit:

I forgot that the array must be set to float with the damn #, I am getting too used with php where every variable is just $Variable.


Thank you though for the help, I am gonna test this now on the game and hope it will works fine (on the small test it worked).

It works like a charm now, thank you!

You're welcome, always happy to help.
