[_] Pre-alpha. Rate my physics pls. Anonymous 08/15/13(Thu)04:18 No.2077688
So i'm making this game, and these are the physics i have so far. I'm just looking for some
feedback on how they feel, as i find it to be very time consuming to change them after you added
a lot of other mechanics on top of the physics (because you usually have to rebalance everything
if you slightly change the gravity or friction or whatever).
Arrows to move.
Thank you for any feedback.

Movement left and right feels like constant accelerations; if this is eventually going to
represent walking/running movement, there should only be acceleration when you first begin to
move, then it will stop once you've reached a certain velocity

You best be using Box2D.

movement left and right are acceleration up to a point (20 pixels per frame (30 fps(600
px/sec))), at which point the jet engine only keeps you moving at the same speed until you let go
of the button.
If you move downhill, you will get some additional acceleration, up to 30 px/frame or 900 px/sec.
Should i make these interactions more noticeable?

i'm not using any libraries other than the ones included in your base flash install,

Why not? Seriously. You can get the source code for a professionally made 2D physics engine with
no strings attached.

I'm taking a bachelors in game programming, starting this semester. I plan on doing a before and
after comparison to see what i learned over 3 years.
This game will be my "before". Wouldn't want to cheat and use other peoples' work for everything.

No bueno

Oh snap, that's a bug.
Thanks, anon!

I see nothing wrong with a continuous acceleration, but my peeve is that jumping slows down the
acceleration and doesn't continue it.
Are you working on a sonic like runner? I assumed so, because he's flatuating fire as
acceleration.

i want a jump that lasts as long as you hold it

Movement is supposed to simulate jet-powered skiing.
What do you mean when you say that jumping slows down the acceleration? When i run the game this
does not occur, which makes me think it might be a bug. Did you jump with the up key, or did you
ski over a slope? What were the circumstances around your jump?
>>2077765
Flying would be overpowered with the other mechanics i'm planning to add in.

Pressing up will fok it up. Also release a fully flat version pls

pressing up will not fok it up i mean, it will slow ya down substantially.

also going right is faster than going left

theres no momentum
>> [_] Anonymous 08/15/13(Thu)06:25 No.2077786
Momentum should continue midair, I think. If you let go of the left/right arrow keys during a
jump, you decelerate midair

Very well, i will fix it for the next version.
Thanks for your input!

Feels like the platforms have a gravitational field around them.
also, on occasion, you sometimes bump an invisible wall when you try to use the bottom ramp.

On the top layer of blocks, I was attempting to see how fast I could accelerate, and I noticed,
that jumping negates the acceleration, which almost feels like its slowing, but I guess its just
not getting faster. Also could be I'm tired as hell lol.

Right, i understand what you mean now.
The speed cap was intentional, and the deceleration in midair was intended to give the player
more air control. I agree that it's silly though, so i will change it to an extremely slight /
barely noticeable deceleration, with the ability for the player to accelerate in the other
direction if they want to stop sooner.
>>2077793
Could you elaborate on the gravitational field? Is this all platforms, only the square ones, only
the slopes, only the upside down(roof) slopes?
Are you able to recognise any specific movement patterns that seem to make it happen, or is it
all the time?
