how do i do ray casting/ ray tracing i really want to make a fps so this would be nice to know

please if you know how can you help me i have been wanting to do this for a while idk know the difference between ray tracing and ray casting i just basically want a 3d game

There's a template here that doesn't use any 3rd party plugins. It's not free but it looks pretty well done. scirra.com/store/royalty-free-game-templates/construct-2-ray-casting-template-4734

Reverse engineering that would probably be the best way to understand it.

Otherwise there is a name your own price, basic template here: alcex.itch.io/retro-first-person-template-for-construct-3

i just basically want a 3d game

Thank me later
