Problems with Gravity.

Hi, I'm new in this forum and I started to use MMF2 4 days ago so, I'm still in the basic learning process. As I've read, making a platform game with the default options of MMF2 is a wrong way, so I started to learning "Fast Loops" tutorials. I read the Fastloop Custom Platform Movement by David Newton (DavidN). But I want to change something about the Gravity.

I want to make a Mega Man X game, so I'm trying to emulate the physics, the engine, but there is a lot of questions bugging me hehe. So first, when jumping, the player goes up and down very fast (at least more fast than the original Mega Man X game), and I wanted to edit that but failed.

I checked the increasing of Y position, and it have this formula: Set Y position to Y("Player")+1. I tried to make Y("Player")+0.5 but it failed (I think is not possible of move 0.5 pixels hehe). So I'm out of ideas, how should I modify the Gravity so the player goes up and down more slower?

I was thinking on make a Counter that have number 5, and each fast loop decrease it by 1, and when it reaches 0, then activate the "Set Y position to Y("Player")+1" event, and start again with number 5 in the same Counter. So that way the process of adding 1 pixel to the position will be slower than original. But I don't know if that could work.

I hope you can help me, thanks!

EDIT: I forgot to ask you something, is there a way to check how many pixels the player jumps or dash in a game like MegamanX so we can easily emulate them? Or it's just by trying? Thanks again.

Did you read the entire tutorial? Also, that tutorial (this is other people's opinion) may be a little advanced for someone new.

The tutorial does use some fairly advanced ideas for people completely new to programming, but it sounds like you have a fairly good understanding of what's going on.

You're right that you can't move an object by less than a pixel per frame - the idea of counting off a value every frame and only allowing a change when that's a certain value will work - I use that in a few places myself when moving 1 pixel per frame is still too fast. However, it might be easier in this case to just lower the amount that the gravity variable is increased per frame (I think it's 0.7 in the tutorial, from memory...) - alterable values can hold values that aren't whole numbers!

There was someone making a Mega Man game like this ages ago - to get completely accurate jumps to the original movement, what he did was to record the jumps in an emulator, then counted the pixels to see how far the player character moved on each frame.

And welcome to the forums, and MMF2 :)

Yes, that's hwat I meant because later in the tutorial, you change grav from always adding 1 to adding 0.5 or something.

Thank you for the answers. I've edited some values and I think I reached almost the same jumping height and speed. Now I'm looking for A.I. tutorials or something because I need to add movement to an enemy.

Also, I'm maybe a noob in MMF2 but I have time editing and programming SMW (Super Mario World from SNES), and I have some knowledge since some things are the same.

And a screenshoot of what I've done:
