Dynamic jump force (by pressing the button)

I'm trying to get the character to jump more or less distance if the button is held down, but I can't find a way to do it.

I've tried modifying both the jump force and the gravity, increasing them if the button is held down, but I can't get anything to work properly or not be "weird to look at".

Sorry for my English.

I assume you are using the Platform behavior.

Set a very high value (eg: 10000000) in this text field:

It could be a solution, but it only works with the default controls. If I assign a button it doesn't work. :(

I found the solution by changing the order of some functions.

Thanks.
