now to modify the inventory system downloaded/added. Its just too anxious currently. to modify a slight complex inventory system currently to change according to this game logic. 

its lucky that we found this inventory and game logic system (which we would buy when we finish game and then increase 100K income level but currently its of free license type) since it has some important game logic components ready. but its slightly complex also. (I mean modification/change of. it has alot intricate components etc) 

but its cool that there is such avail library. since i am not any blueprint expert, it would had taken me alot time to prepare such inventory. so its a great service that a coder made such library avail with also free license. (but to be bought after 100K income threshold) 

aha this library it is ->

Modular Gameplay Blueprint Systems | Fab

cause I am not any expert in blueprint of unreal or unreal game engine any yet so this library  benefits this project alot actually.

I think it might add 2 months more time frame to write some of the required functions myself maybe. since I am not used to game engine concepts yet of this unreal game engine. so finding this library were really awesome. 

hmm some forward IK stuff to investigate -> e.g. how to raise characters arm some in air to point towards something. i mean animation ARB system of controller. that yet had not been learnt. but yesterday I learnt basic ARB concepts here and there. and so would require to modify the animation system to add that when e.g. shooting stuff against hostile life forms attacking etc or so. 

i think still with all challenges maybe end of this month like time frame is yet too optimistic. but i think most of game logic/systems would be ready by then. but i think maybe some bit further publishing time frame might delay (but not much, at most 2 weeks delay alike i think so)
