How Graphics Were Added in Old-school 8-bit/16-bit Games ?

Abhishek Rawalwhen there were no IDE ,no OpenGL .

What about gedit ?

Apurwa.ThakurWhat about gedit ?

I don't think there was gedit in 1980's, was it available at that time ? 😨

Oohh!i didn't get you are talking about initial time.i haven't much knowledge About programming language.but during the time you are talking about

1.1952-dogle created first graphical computer game was programmed on a EDSAC vaccuum-tube computer, which had a cathode ray tube display.

2.after that a MIT PDP-1 mainframe computer programming used in space war.

Abhishek RawalSo, suddenly I don't know what happened to me, I am very much attracted to 8-bit games & 16-bit sega games. i want them in Raspberry Pi.

A question popped in my mind : Back then, when there were no IDE ,no OpenGL . How did they created game & added graphics using ASM ? I mean did they used only ASM for entire game ?
Which method did the developers used in old times to develop 8-bit/16-bit games ?

Eager to know.

From what I can remember, in ASM u can use two modes for displaying data on the screen, ie Text mode and Graphics mode .
There were instructions (specifically interrupts) to change from text mode to graphics mode, the resolutions were limited of course 😀.
Using the instructions games could be developed, but the development was of course difficult and time consuming, and the games were simple.
Then we come to 16 bit when C was popular choice for development. If u have used Turbo C , you may know there is a set of graphics libraries to work in graphical mode.
And the games were better than those in 8 bit era.
Hope this answer some part of ur question 👍

I am reading Assembly language programming by Duntemann & I didn't came up with any theories about any instruction which converts texts into graphics. Am I missing something ?

Bit off-topic, but please suggest me a nice book for Programming Game using Assembly language which can solve all my confusions.

I studied a little bit about this from my professor once (for fun, in free time) so doesn't know any good books about it, however I searched a bit and found two tutorials which may get u started, check these out:
