Problems with rounding the player's y-position in a draw.

[KauanGamer2130]

I created a mechanic where the spin dash increases and decreases in size, replicating the famous "squash and stretch" effect from Sonic Superstars. However, it was necessary to change the player's position on the y-axis during this animation to prevent the sprite from floating, since it uses the same origin as the sprite in its original scale. The problem is that when releasing the spin dash, depending on its previous scale, it can cause the player to end up 1 or 2 pixels lower than usual due to rounding.

This is because you're essentially rounding player's y coordinate before they are even drawn which you should never do. Do not floor y while assigning it to y_spindash. You should restore player's position as it was, without applying any rounding to it

[TrianglyRU]

so basically

var base_draw_y = y;
y += draw_offset_y;

// Draw (at floored position)
event_inherited();

y = base_draw_y;

I also discovered that, in addition, it was necessary to set draw_offset_y to 0 in the spin dash function in the part where the spin dash would be released.

Thank you!

i feel like you could've just made the squash-and-stretch effect in the spindash anim itself. would've been much easier for sure

Yeah, but since these are placeholder sprites, it was easier to do it with code because that way it works with all characters and any sprite!
