Systems and methods for improved collision detection in video games

A system for detecting a solid surface level relative to a virtual character in a virtual environment of a video game, the system comprising at least one server executing a plurality of programmatic instructions, wherein said programmatic instructions:

• define a first geometric model, wherein the first geometric model has a first shape and first size and wherein the first geometric model at least partially bounds the virtual character;
• move the first geometric model vertically, from a first position to a second position, by a predefined first distance;
• determine a first image obtained by projecting the first geometric model, in the second position, onto an axis of a world coordinate system defining said virtual environment;
• determine a second image obtained by projecting the solid surface level onto said axis of the world coordinate system;
• determine if a first condition is fulfilled, wherein the first condition is indicative of an overlap or intersection between the first image projection and second image projections;
• and
• determine at least one of an adjusted position, an adjusted direction or adjusted velocity of the virtual character if the overlap or intersection with the solid surface level is detected.
