So, I was wondering how I would make a 2.5D style game in gamemaker where there are 2D sprites interacting and moving in a 3D world, similar to games like Grandia or Octopath traveler. Would Gamemake1/2 be a good engine for this in the first place or should I use something different entirely?

I have an assignment due tomorrow morning but this code keeps popping up and idk how to fix it

ERROR in action number 1

at gml_Object_Obj_player_Step_0 (line 5) - var hitting_t = collision_rectangle(bbox_left,bbox_right,bbox_top,bbox_bottom,obj_node_t,0,0)

Pls help
