Many consoledesktop 2d platformers tend to not use the physics engine in favor or pixel-perfect control, but I would guess many mobile games do use physics engine for the endless-runner games.

But I would advise that you try both if possible to find what works for you.

Super mario world, for example, has different falling rates for each character powerup state and the concept of ground or platform.

Like so many others, we started out using the (Box2D) physic.

Now that I know that box2d is the key I will have to do many more experiments.

So far so good: - player moves leftrightjump with keyboard - moving platforms - bouncing enemies - slopes.

This works but only when the player touches the joints of my ground Do you know how I can fix this please Some piece of code: in the player class: self.numfeetcontacts false.

It is quite difficult to get the things I would like to have in a platformer.

What I have working: animated player, player can go left right and jump (tested with 3 variations impulse, force,.), moving platform (jittery), pass through platform, enemies (but no firing yet), slopes (thats why I wanted to try liquidfun) Whats missing: firing something (why bullets), takingmaking damage, fixing the jittery, moving platform, and a lot lot more.

PS: I put some comments in the code PS2: the code is quite short for what it is PS3: liquidfun is quite fun.

Id have the game running all the time with the scenemanager just being used to change the state machine.

When you begin you do it the way that makes sense to you then overtime when you learn best practices you adapt.

I found out why my player was jittery on moving platforms and fixed it Now we have a bridge, the player can shoot (but no collisions with enemies yet).

Some thought about this: - I noticed that for a platformer, liquidfun (box2d) is the way to go (cf: other engines) - I learnt a lot from iforce box2d tutorials - it is a bit harder than cbump but we can achieve so much more I think that I will push it more to make a yt tutorial The game is quite fun to play on a mobile I am quite happy with the controls.

I searched this forum to get some help and I came across your car demo and it is great What has your game became (become) It looked very promising and I am quite a fan of those top down racing games Gideros is a great engine but we have to dig.

One problem I may have is building the level RUBE looks super cool and I have read that TILED also fits but I am not there yet.

As of now I am building my level pixel by pixel I may ask for your help later if I am not happy with how I build my levels.

I have lots of ideas for multiplayer games but Gideros doesnt support that out of the box You can use tiled to make levels but its slow going.

In your code you load the tiled map and iterate through the objects layer and use that data to generate the Box2D shapes you need.

Im not sure how you are doing things right now but I found Chain Shapes to be quite good.

Anyhoo. hit me up if you need any help P.S, I also gave up on my Gideros book for now because Im studying full time.

Id like to get back into it but I feel myself becoming more and more detached from Gideros as time goes by.

Gideros can be frustrating sometimes but trust me this is a great engine (if not the best engine I have used so far) Please dont give up on us, we need you.

The only little problem I see is building the levels I place every single items by hand.

Its ok if you build a couple of levels but more than that it can be cumbersome.

Personally I dont mind building the levels by hand and I havent tried Tiled editor nor RUBE.

I am using the wonderful Contour.lua class by n1cke and I have read you can build levels using it Some tutorials to come.

Wow I love that physics rope there Many hyper-casual games are physics-based nowadays, with simple graphics.

With liquidfun you can build many interesting games and I think I found the missing link from doing what I use to do in an other engine.
