wow i dont understand how you got to the conclusion i want drag and drop, i despise drag and drop, aka visual programming, it disgusts me, i dont even like 3d scene builders. unity sucks, and i never saw game maker as an option.
im a programmer close to 10 years, i mostly did database based web aplications.
i started game programming with flashpunk an as3 flash framework, the competitor of flixel (most complex thing i did lately is to implement flow field algorithm for an rts game its actually a nice algorithem).
it(flashpunk) uses entity (a as3 class) and entity derived/extanded class as "actors"/game objects, an entity has most things you need for game objects : movment (with solid hit detection) hit collision detection (box and pixel based and even raycasting), rotation,alpha, basic maths (angel between point/entity, distance) sprite/image manipulation/animation (including tween), input handling,etc etc.
each entity has a type so you can get entities with "get by type" or collide by type.
thers also world, itsl like a screen, each world holds entites, while non active worlds entites are not active or visable, you change world to move between screens.
for example a pong game with this framework:
worlds: start screen, game screen, game over
entities:
paddle
ball
score
buttons
edit:the big thing is that its oop meaning a class encapsulates data and functions (methods) so all you need to do is : world.add(some_entity) , and dont worry about it the world will update it as it keeps a list of entites, and to remove its as easy world.remove(some_entity), no need to loop anything update a list/array,display object like sprite remove does it all.
btw agk has this when you add or remove a sprite(and images and sounds etc), why dont they make a way to do this with user defined types? that would make my life much easier with less boilerplate code.
i can do all this without that framework, as proof over the years i ported it(flashpunk framework) to at least 10+ engines and languages (i know it very intimately):
my first attempt after i was told flash is dead(decleard dead), there were no class in js yet so i used prototypes (the engine is dom based):
https://github.com/yoel123/yoel-html5-game-engine-tutorials
later i ported it to phaser js:
https://github.com/yoel123/yoel-phaser-js-framework
and then to java with slick 2d (java has oop):
https://github.com/yoel123/yoel-java-slick2d-framework
it lacked mobile so i ported it to corona sdk, lua has oop, but its a bit clumsy:
https://github.com/yoel123/corona-sdk-picking-sticks
i will also make a picking sticks for agk.
i also ported it to unity (i dont have the files).
ported to naalaa ( a basic dilect):
https://github.com/yoel123/naalaa-avoider-game
naalaa has types but no oop but i manged

im still pissed thers no proper refrence variables like:
a = "bla"
b = a
b = b + " holubalu!"
print(a)//prints bla
print(b) //prints bla holubalu!
dosnt seem anoying? lets see
im_a_very_long_object_array
.pos.x = 5
//im a short var to refrence the line before for readabilety and fun
ex = im_a_very_long_object_array.pos.x //short for entity x
speed = 1
ex = ex +speed
print(ex)//prints 6
print(im_a_very_long_object_array.pos.x) //prints 5.....why me why
so i have to use im_a_very_long_object_array.pos.x to update that entities pos (or create a function for that) .
agk seems like a very powerful toll with many platform support and everything you need to make a game out ob the box the basics and luxury features.
i would prefer to use its basic scripting language (if i wanted cpp i would have used a diffrent free engine).
somtimes simple is better for faster devlopment.
but no oop is very hard for somone who is very used to and fond of oop.
again it dosnt even have proper references.
if somone has an advise or a workaround (or a feature i dont know about) it will help me a lot.
