Expert blueprint for platformers emphasizing movement feel, level design, and player satisfaction.

NEVER Do (Expert Anti-Patterns)

NEVER multiply velocity by delta before move_and_slide(); the method internalizes the timestep.
NEVER skip Coyote Time (approx 0.1s); without this grace period, jumps will feel unresponsive when walking off ledges.
NEVER ignore Jump Buffering (approx 0.15s); players expect to jump the instant they touch the ground if they pressed the button early.
NEVER use a fixed jump height; strictly implement Variable Jump Height (cut velocity on release) for player expression.
NEVER forget to scale gravity by delta before adding to velocity; gravity is an acceleration and must be frame-rate independent.
NEVER rely on discrete collision for high-speed movement; strictly use CCD_MODE_CAST_RAY to prevent tunneling through geometry.
NEVER use move_and_collide() for standard traversal; it lacks the slope/stair handling of move_and_slide().
NEVER check coyote or buffer timers using exact equality (== 0.0); strictly use is_equal_approx() or >= 0.0.
