Hi, I was doing some simple tests with float and I didn’t get the result I wanted to. I had a health variable and each time I pressed E I wanted to reduce some health until I got to 0.0 or under. It worked if I used 0.25 and 0.1 and 0.5 and so on but it didn’t work with 0.2.

I found the node “Nearly Equal (float)” and it worked with that.

You can see here that it first goes to 0.0 and then in goes to death.

Hi AirBlaze,

This is a known issue. What you are seeing is a Float Point Error and it’s just a quirk of the engine. The NearlyEqual node you are using was implemented into earlier versions of the engine to accommodate this issue.
