Delta

hello my friends, like you i was often confused by when i should use delta, and am still learning, but this is what i have been taught so far.

let V : Velocity
let P : Position
let D : Delta

using (move_toward, move_and_collide, ect)
 - Calculating the effect of acceleration (units/second^2) over time. ✅ (V += *D, V -= *D)
 - Setting an instantaneous speed (e.g., jump, dash start). ❎ (V = *D)
 - Calculating the distance to move this frame from a speed (units/second).	✅ (P += *D)

using (move_and_slide)
 - Applying acceleration (e.g., gravity) to your velocity vector.	✅ (V += *D, V -= *D)
 - Setting a new speed (e.g., a jump or a constant movement speed).	❎ (V = *D)
 - Passing the final, calculated velocity to the function.	❎ (V *= D)
