[51:51][Q&A][:speech]
|
|
[53:15][@Mr4thDimention][I'm a little unclear about what pressure is keeping you from doing the Z math exactly like you would in 3D]
|
|
[53:28][Blackboard: Conceptualising Z]
|
|
[59:45][@rdwindmill][Where are you going to draw the labels for entity properties?]
|
|
[1:00:05][@Ikkir_Isth][Did you decide which 'awesome thing' to do for tomorrow's stream?]
|
|
[1:00:25][@ijustwantfood][What do you define as a good game design?]
|
|
[1:00:34][@garryjohanson][Curious if your decision to design your own game engine has more to do with you furthering your own skill level, or do you have reason to not trust the middleware solutions you have seen in the past?]
|
|
[1:04:42][@ciutchism][Did you play Warcraft III at all or any of the mods? I need some help replicating some of the movement mechanics from one of the games and nobody understands me when I describe it. Willing to pay PayPal to whoever can code it. I'm betting it's honestly somewhat simple]
|
|
[1:05:41][@StarchyPancakes][Would it work to render it in full 3D and rotate all the sprites by 45 degrees (or whatever angle the camera is taking)?]
|
|
[1:07:51][@rdwindmill][I understand the art is drawn in the 3/4 view. Is the camera at an angle or top down?]
|
|
[1:10:34][@graeme7][The 3DS Zelda games do the 3D-at-an-angle for 2D]
|
|
[1:11:33][@garryjohanson][So I'm making a full 3D RTS that uses a mouse with a joystick built in so you can adjust where you are looking with the joystick and still use the mouse as a mouse for unit selection. Do you think that is an untenable idea for a product? If you had to buy a new mouse for one game, would you be like "nooo"?]
|
|
[1:12:12][@abnercoimbre][Did you ever end up playing The Mother series? Still on your TODO?]
|
|
[1:12:29][@rdwindmill][I kind of jumped over 100 episodes so I don't understand what the issue was with the debug selector. Was the issue with the hitbox depth only or also the position?]
