I can't understand "-" in xn = cellsize - (player.x / cellsize) * cellsize, timing 2:39. I was expecting xn = cellsize + (player.x / cellsize) * cellsize. (player.x / cellsize) - tell us how much cells the player walked throng x axes. (player.x / cellsize) * cellsize - we convert cells walked for pixels walked. this value corresponds the left side in the cell where player is currently. cellsize + (player.x / cellsize) * cellsize - give us the right side of the cell where player is currently, in others words, the y value where first vertical intersection occur.

this was so confusing. feel like lot of information is omitted and not explained in details. im not sure how it is "fully explained". Not even sure if the issue he just assumes others know or he incorrectly explained.

For wall colour, you can change the colour the lines are drawn depending on the distance to the wall that you calculated, so it gets darker the further away the walls are

@giovannicesaramorim9adigan961 6 ай бұрын

How do you know when you have hit a wall? I'm thinking about using a matrix, but wouldn't that just be infinitely small points in the determinate coordinates? The numbers in the matrix aren't lines

that part does not make sense. probably a mistake. (py-(py/cellsize))*cellsize will always equal 0

@hakansuner2578 6 ай бұрын

It uses the formula (cellsize-(player.x/cellsize)*cellsize) for the same calculation when checking vertical intersections. It makes sense when the same formula is used for the y position. I think there was a little confusion

@unmandarinoalgiorno...9321 2 ай бұрын

@@ringzero3260 it's because in programming, the result of py/cellsize will be an integer. For example 5/3 will be 1. But i think the formula to count xn when checking vertical intersections is probably wrong. From what i understand, it shoud be xn = cellsize - player.x + (player.x / cellsize) * cellsize

hello, i have a question. when u calculate xs, shouldn't xs = ys/-tan(angle)? also, shouldn't i check if player is facing upwards or downwards, becouse when it faces upwards yn = Player.y/cellsize * cellsie and when it faces downwords yn =Player.y/cellsize * cellsize + cellsize

I love your video; however, I still have a few questions. For the Horizontal intersect at 2:00; the Y nearest has the Player.y over cell size then multiplied by cell size witch would cancel each other out then by subtracting Y nearest, would output a zero no mater what the two variables equal. Did you mean to put (Player.y (Player.y/cellsize)) cellsize instead of Player.y (Player.y/cellsize) cellsize? I also noted at 2:32 you used cell to subtract, divide and multiply when the previous step only used step to divide and multiply; y-(y/s)s and s-(x/s)s (used letters for simplification) . It was a great video and helped me out tones, I'm just a little lost at a few parts.

@weirddevers9165 3 жыл бұрын

player.y/cellsize should be evenly divided. For instance if player.y is equal to 131 and cellsize is 64 then player.y over cellsize equals 2. In this case the equation gives the following result yn = 131 - 2*64. If you still have questions I’m willing to answer
