45 degree Overhead view

[Xenith]

Since everyone seems to be quiet, i'm thinkin' of doing a little project to get into the 3d stuff, but i don't want to ask at the gmc, since everyone's so uptight there.

Anyways, i wanna make a 3d game, but i want it to have an overhead view like zelda, secret of mana, or pretty much any 2d rpg.

also since there's not much going for Game Maker in the polygon intense graphics department, i want to make the characters 2d

i've seen this one example forums.gamemaker.nl/index.php?showtopic=209363

but what he did was make a wall have a texture on it, and i tried to put in an animated sprite but it would always stay on one frame.

then i checked out this one
forums.gamemaker.nl/index.php?showtopic=201957&hl=

but i couldn't fin out what code did exactly what in it.

hope you understood what i was saying.

to make it animated put
tex = sprite_get_texture(spr_player,image_index);
in the draw function instead of the create function.
On jools example for some reason you have to set the image speed or it doesnt work, i used
image_speed = room_speed
in create event.

thanks, that worked. i'm gonna test out some other stuff


[edit]

okay i got another question, i've been fiddlin around with this stuff, and made sense of alot of it. but i don't know why i can't make it so the animations stop when the buttons aren't pressed and move when they are

the last gm i used was 5.4 or something, it was the last one before 6.

anyways i don't know if they changed how the if cases and the bracketing or something

5.3c

The if statements and cases and such remain the same. Some functions and variables and such have been deprecated. One of which you should really look out for is image_single, which was deprecated in the switch from 5.3 to 6, in favour of image_index and image_speed (used together). If you still use this function, it will work, but may produce unexpected results.

[Xenith]

what i tried to do was check whether the buttons were being pressed and if none of them were the image_single would go to 0, i dunno though, it seemed to keep the character on ths still frame.

[IsmAvatar]

like i said, image_single was deprecated and may not work as expected. You should replace every occurance of it with its image_speed and image_index counterparts.

image_single = a
converts to:
image_speed = 0
image_index = a

image_single = -1
converts to:
image_speed = 1 //or whatever image_speed is normally


My website has a movement script called Priorities Movement or something which I had to remove the link to when I updated it because I had used image_single, and it no longer worked.

[Xenith]

thanks, what i had was this
x1 = x-8;
x2 = x+8;
y1 = y;
y2 = y;
z1 = 16;
z2 = 0;
global.randix = randi.x
global.randiy = randi.y
if global.randi_dir = "left" {tex = sprite_get_texture(randi_left,-1)}
if global.randi_dir = "right" {tex = sprite_get_texture(randi_right,-1)}
if global.randi_dir = "down" {tex = sprite_get_texture(randi_down,-1)}
if global.randi_dir = "up" {tex = sprite_get_texture(randi_up,-1)}
if (not keyboard_check(vk_up) and not keyboard_check(vk_down) and not keyboard_check(vk_left) and not keyboard_check(vk_right))
{image_single=0}

i just exchanged image_single with image_index and it works great now.

[Xenith]

what happened to the draw_text_sprite function?

also if this still works, how could i get it to work in 3d? do i just add z to it?

create

alarm[0] = room_speed
image_speed = .3

alarm0

if random(2) < .5 {
speed = 0
}
else {
direction = floor(random(4)) * 90
speed = 3
}
alarm[1] = room_speed

alarm1

speed = 0
alarm[0] = room_speed  

step

switch direction {
case 0: sprite_index=g_hair_girl_right;break;
case 90: sprite_index=g_hair_girl_up;break;
case 180: sprite_index=g_hair_girl_left;break;
case 270: sprite_index=g_hair_girl_down;break;
}  

if (speed = 0)
then {image_speed = 0;}
else
{image_speed = .3}
depth = -y + sprite_height
if image_speed = 0 then image_single = 0
else image_single = -1

collision event with hero makes the npc bounce
collision event with block makes the npc bounce

[edit]
if x < view_left[0] { x = view_left[0] }
if x > view_left[0] + view_width[0] { x = view_left[0] + view_width[0]}
if y < view_top[0] { y = view_left[0] }
if y > view_top[0] + view_height[0] { y = view_top[0] + view_height[0]}

what have those functions been replaced with?

[shad0w]

view_left=view_xview
view_top=view_yview
view_width=view_wview
view_height=view_hview

I think draw_text_sprite is still there, or an equivalent- I remember using it just recently.

Im not sure what your other question is.

[IsmAvatar]

To make something 3d, you need to add a draw event to it. You handle all the 3d drawing yourself using the d3d_ functions.

[Xenith]

thanks,

i know how to make things 3d, but i thought, that -x and -y etc all worked in the 3d world and i was just wondering and i was just wondering if i'd have to bother adding the z axis if i wasn;t needed.

[shad0w]

Nope, it's not needed if you simply decide to not have any varying heights.

[Xenith]

thanks

[IsmAvatar]

not needed, just put a 0 in there every time it asks for z - except for the camera, in which case you'd put a 1 in for the yaw z.

[Xenith]

okay, image_single was workin for me, but i could never change the speed no matter what i used. (unless I changed the room speed)

so i tried image_index = -1 and image_speed = 1 but then the sprite would keep getting stuck on the 6th frame, is there like a new code to get it to cycle?

[edit] i fixed it but i'm not sure how the animation cycles through even though i didn't tell it to. does it do it automatically now?

here's the coding

create

image_speed = .4


step

if (not keyboard_check(vk_up) and not keyboard_check(vk_down) and not keyboard_check(vk_left) and not keyboard_check(vk_right))
{image_index=0}


left

x-=4
sprite_index = boy_wleft


up

y-=4
sprite_index = boy_wup


right

x+=4
sprite_index = boy_wright


down

y+=4
sprite_index = boy_wdown




i tried putting image_index = -1 and image_speed = 1 in the directional buttons but the nimation would just stop on the first frame, but i removed them and they worked. so does anyone know exactly what in my coding got the sprite to animate?
