Simple Codes by 3d

Here are codes that people need alot, that i made and codes I've found. If you have a code you want to submit, post it in a comment and i will add it, pm me, or email me.

Look at mouse

image_angle=point_direction(x,y,mouse_x,mouse_y)

Create an object where your object is standing.

instance_create(0,0,obj_object)

opens up/closes 3d mode

d3d_start()
d3d_end()

how to do the relative selection in code.

speed+=1
vspeed+=1
hspeed+=1

destroy

instance_destroy()

how to code with a keypress that is a letter

if key_press(ord_"W"))

How to do passwords

go to next room

room_go_to_next()

This is for MAJOR n00bs. Except for the last few.

yeah. or ppl thats are AMAZING, but use D&D only.

Easy value swapping (true becomes false, false becomes true):

Code:

boolean = !boolean

Easy gravity:

Code:

gravity = place_free(x, y+1);

Easy auto-tiling:

Code:

grid_x = argument0;
grid_y = argument1;
obj = argument2;
image_index = 1 * place_meeting(x, y + grid_y, obj) +
              2 * place_meeting(x, y - grid_y, obj) +
              4 * place_meeting(x + grid_x, y, obj) +
              8 * place_meeting(x - grid_x, y, obj);

...Used with a tileset like this:
Drawing a default sprite (pro)

Code:

draw_sprite_ext(sprite_index,image_index,x,y,image_xscale,image_yscale,image_angle,image_blend,image_alpha);

Drawing a default sprite (lite)

Code:

draw_sprite(sprite_index, image_index, x, y);

Text alignment (centered)

Code:

draw_set_valign(fa_center);
draw_set_halign(fa_center);

correct.

3d, your code's have several errors in them. Hardly helpful to beginners, e.g.

it is room_goto_next() NOT room_go_to_next();

And it is NOT if key_press(ord_"W")), it is
if keyboard_check(ord('W')), there is not function called key_press.

And as for this

Create an object where your object is standing.

instance_create(0,0,obj_object)

This will only create an object in the top left hand corner of the room, try it.
If you want to create an object where you stand, do this.

Code:


instance_create(x,y,obj_object);


I hope this clears this up for you, we don't want to mis-inform/confuse beginners!
