The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Time to get rid of the old ugly Get Ready display. And put up a new ugly one.

step62.png

The changes are pretty easy, we modify our DisplayGetReady routine to display the sprites now (and store the old sprite settings):


;------------------------------------------------------------
;displays get ready

lda #40
sta LEVEL_START_DELAY
lda #0
sta SPRITE_JUMP_POS
lda VIC_SPRITE_ENABLE

lda #$80
sta VIC_SPRITE_X_EXTEND

...and then the remove routine to restore the previous sprite setup:


lda SPRITE_ENABLED
sta VIC_SPRITE_ENABLE
lda SPRITE_MULTICOLOR
sta VIC_SPRITE_MULTICOLOR
lda SPRITE_POS_X_EXTEND
sta VIC_SPRITE_X_EXTEND
lda SPRITE_POS_X
sta VIC_SPRITE_X_POS
lda SPRITE_POS_X + 1
sta VIC_SPRITE_X_POS + 2
lda SPRITE_POS_Y
sta VIC_SPRITE_Y_POS
lda SPRITE_POS_Y + 1
sta VIC_SPRITE_Y_POS + 2

Also, remember, tables, tables, tables?
