Assume we have a player on a map, whereby the grid is represented as a floating point.
When a player is moving, they have an
How to do you properly apply their movement each gametic?
By that I mean: do you keep nudging the player forward by one map unit and repeat that by the velocity? Where is that fine line where I say "we don't go any smaller movements than this like 0.5, or 0.25, etc"
Further, is there a way to optimize this to be able to make movement fast computationally? I thought of having some kind of blocks where you can quickly check if you'd intersect anything and make some optimizations, but I have no idea if this is good, bad, or how it should be done.
Update: Suppose you have a projectile traveling 100 map units North, and it would collide with an object 50 map units North of it. In the period of one world 'ticking', would you just halt it in a dead on collision (assuming the line is impassible), or would you detect a collision and then do something after it since that remaining 100 map unit velocity (like maybe if it's on an angle then cancel its Northward momentum and continue trying to move it to the East/West.
