Help for the custom engine by David Newton

[idunno]

I have copied(Well, for now, i want to do some changes of course.)David Newton engine by tutorial(Gravity and Horizontal movement) and i need help for the moving speed. The engine don't seems to take decimal, and i want speed between 2 and 3, because i'l be using multiple character and i want the speed to slightly differ from character to character. Can anyone help me with the matter of using small change of speed, or changing the speed to smooths changes. I tried decimal and dividing the "Horiz"("Player") loop setting. thanks anyone who help!

[Sumo]

it should take decimals. Try adding a 0 before the decimal. So instead of writing .25 write 0.25

[RickyRombo]

And if you're dividing, divide by 3.0 or whatever.

[idunno]

Nope, no difference between 2 and 2.5. I'm using the decimal in the Horiz Hidden Value, so maybe the problem is around that. Tried dividing(In the start loop Condition)by 2 and 10, but any number that were divided and were in decimal, seemed to get rounded up.

[idunno]

The rounding up were strange, however. It always was rounded to the lower number Ex: 1.9 were rounded to 1. Like if the decimal were ignored.

[DavidN]

The problem here is that the object is always positioned [Horiz] amount of pixels to the left or right by a fastloop, and you can't run a loop a fraction of one time, so the part of the number after the decimal is ignored. For moving an object a non-whole number of pixels, you would need to keep two values to record its "virtual" X and Y positions, and then modify those with the movement mathematics, finally continually setting the object to those positions. That's going to require a bit of a rethink of the engine, though...
