I was able to make a good assembly of what is happening and killing me for weeks, and I really wanted to know if it was my mistake or just the keys pressed too fast, or the rendering delayed? to deal with the problem, because I'm not finding the culprit for doing so.
This happens when for example I go from diagonal down-rigth to left, and right, then I go back down, I make moves like that, fast, it does not always happen, but enough to disrupt the game.

#LEFT
if Input.is_action_pressed("left"):
direction += Vector2(-1, 0)
#RIGHT
elif Input.is_action_pressed("right"):
direction += Vector2(1, 0)
#UṔ
if Input.is_action_pressed("up"):
direction += Vector2(0, -1)

direction = direction.normalized()*velocity

Do not be fussed with the codes, it's very simple what I'm trying to do, I want to move the player while I generate my world, it works perfectly in the 4 directions, but when it involves the diagonals, it does not go as expected. I'm painting like this, I have two rects that I compare to each frame, I take the retagunlo of the interception and calculate where I should paint or erase.
Video of what is happening:
http://www.dailymotion.com/video/x6286px
But there are these flaws not only by pressing too fast, it also happens in slow motion, while being diagonally down-right and then left or left-right and then back to right, moving on the diagonals seems to be the problem, I've tried a lot of shapes, I have almost a notebook all scribble trying to figure this out, I tried with diagonal checks too and I get the same result, today I lost another day, and it does not leave the place, I'm weeks like this, when I think I fixed it, not really.
I'm using godot.
Up 1:
With @Ryan1729 response I realized that I was really thinking the wrong way, but I try to fix my logic by doing something like below and the error continues, I'm confused:
if direction.x != 0 || direction.y != 0:
var vetor_normalized = direction.normalized()
if abs(vetor_normalized.x) < 1 && abs(vetor_normalized.y) < 1:
var vx = Vector2(direction.x, 0)
var vy = Vector2(0, direction.y)
vx = vx.normalized()*velocity
move(vx*delta)
vy = vy.normalized()*velocity
move(vy*delta)
else:
direction = direction.normalized()*velocity
move(direction*delta)
Up2:
Now I have done so, it seems that solved the flaws, but others appeared, which I still do not understand, this issue of 0 confuses me too much.
var oldPosWorld = Vector2(0, 0)
var rect_tileMap = Vector2(-32, -32)
func load_newMap():
var posPlayer = Vector2(int(player.get_position().x/32), int(player.get_position().y/32))
#LEFT
if posPlayer.x < oldPosWorld.x:
pos_tileMap.x -= 1
posWorld.x -= 1
gen_data(Vector2(posWorld.x, posWorld.y), Vector2(pos_tileMap.x, pos_tileMap.y), Vector2(1, size_rectMap))
#RIGHT
elif posPlayer.x > oldPosWorld.x:
pos_tileMap.x += 1
posWorld.x += 1
gen_data(Vector2(posWorld.x - 1, posWorld.y), Vector2(pos_tileMap.x + 63, pos_tileMap.y), Vector2(1, size_rectMap))
#UP
if posPlayer.y < oldPosWorld.y:
pos_tileMap.y -= 1
posWorld.y -= 1
gen_data(Vector2(posWorld.x, posWorld.y), Vector2(pos_tileMap.x, pos_tileMap.y), Vector2(size_rectMap, 1))
#DOWN
elif posPlayer.y > oldPosWorld.y:
pos_tileMap.y += 1
posWorld.y += 1
gen_data(Vector2(posWorld.x, posWorld.y - 1), Vector2(pos_tileMap.x, pos_tileMap.y + 63), Vector2(size_rectMap, 1))
oldPosWorld = posPlayer
The movements of the right and bottom are right, the problem is those of the left and above that is left over this empty space(ie dealing with the negatives ).
If I put x - 1 on the left to solve the problem, this happens to me:
I solved this by changing:
var posPlayer = Vector2(int(player.get_position().x/32), int(player.get_position().y/32))
by checks like this:
if ((player.get_position().x)/32)
but now I get this by going to the sides and then up:
Up 3:
I'm not going to put my mind to it, so as not to get frustrated if I'm mistaken, but by the tests I did the failure stopped. The code would look like this by assigning int (player.get_position (). X / 32) separately to oldPosWorld.x, this respectively for y as well, since before I was assigning the position to the player only once the postPlayer variable, this caused errors , when you entered the up-down if, as it was still with the previous position of x, doing so updates everything in its right time.
is still so to the left and up:
I do not quite understand why, and frankly not so soon will I know, I'm too tired to look at it. But I'd like to understand not to err. Apart from this it seems to be happening now as expected.
#LEFT
if int(player.get_position().x/32) < oldPosWorld.x:
rect_tileMap.x -= 1
posWorld.x -= 1
gen_data(Vector2(posWorld.x, posWorld.y), Vector2(rect_tileMap.x, rect_tileMap.y), Vector2(1, size_rectMap))
oldPosWorld.x = int(player.get_position().x/32)
