We are travelling at the moment, and my boys are playing the original Tombraider on their laptop. They love the level design and jumping and grabbing ledges. The jumping mechanism is annoying at first but once you master it, it gives a real feeling of satisfaction when you nail the jump. It’s a really good game, even in this day. I think the main thing that makes jumping like this work in games is that you need to model the “run up” to the jump and the inertia of the jump.

Looks good kinda like she’s trying to walk to make things bounce.
I’d play the game and I hated the old tomb raider games.
You must put some step-by-step game guide for amateurs and game programming learners for step-by-step game development, so that anyone who is interested to build game from scratch will know how to do it actually 
sure thing but it hard to explain what exactly im doing, botching allot of weird stuff together

looking for collaboration on the side scroller platformer engine.
would be used for this game and any others making it easer for more platformer games to be made
pm me for interest
I might be interested! I sent a pm with more details.
Wish I could code and I’d help.
wish no more, just do it

Cool , that will be my next project, currently working on a wooden Alexa just waiting on a few parts to arrive wire it up see if it works then build the case
need some help with collision + physics
for platfrormer
code so far works on hardware

I have no educational background for programming and I am using C for nearly 1 year. I am still beginner in programming and English. Sometimes it’s hard to understand English for me. Because we have one of the worst educational system in the world. I’m trying to improve my skills
