Gamemaker Studio 2 Gml ◉ < UPDATED >

Changing Sprites:

sprite_index = spr_player_run;
image_speed = 0.2; // Frames per game step (0.2 = slow, 1 = normal)
image_index = 0;   // Reset animation

Manual Animation Control:

// Only animate if moving
if (hsp != 0 || vsp != 0) 
    sprite_index = spr_player_run;
 else 
    sprite_index = spr_player_idle;
// Sprite flipping
image_xscale = sign(hsp); // Flips left/right (if hsp is -1 or 1)
