As often standard in games, I want the game to mirror my sprite. So I tried to use image_xscale as I used to do in GM7, but it crashed my game. Is the code bugged or am I doing something wrong?

Create Event:
//variable for turning
global.turned

Step Event:
if keyboard_check_pressed(button_right) {global.turned = 0}
if keyboard_check_pressed(button_left) {global.turned = 1}

End Step Event:
image_xscale = global.turned

In my game the character is suppose to be able to flip gravity around by pressing up and the jump button, but as soon as he hits the roof he gets stuck and all I can do is flip gravity again to get him off. Does anyone know why he gets stuck?

Create Event:

global.grav_switch = 270
button_right = vk_right
button_left = vk_left
button_up = vk_up
button_jump = ord("Z")


Step Event:

gravity_direction = global.grav_switch
if keyboard_check_pressed(button_jump) and keyboard_check(button_up)
{
if global.grav_switch = 270 {global.grav_switch = 90 exit}
if global.grav_switch = 90 {global.grav_switch = 270 exit}
}

if global.grav_switch = 270
{
button_up = vk_up
if place_free(x,y+1) {gravity = 0.5} else {gravity = 0}
if keyboard_check(button_left) && place_free(x-3,y) {x-=3}
if keyboard_check(button_right) && place_free(x+3,y) {x+=3}
if keyboard_check_pressed(button_jump) && !place_free(x,y+1) {vspeed = -8}
if keyboard_check_released(button_jump) vspeed = max(0, -8)
if vspeed > 10 {vspeed = 10}
}

if global.grav_switch = 90
{
button_up = vk_down
if place_free(x,y-1) {gravity = -0.5} else {gravity = 0}
if keyboard_check(button_left) && place_free(x-3,y) {x-=3}
if keyboard_check(button_right) && place_free(x+3,y) {x+=3}
if keyboard_check_pressed(button_jump) && !place_free(x,y-1) {vspeed = 8}
if keyboard_check_released(button_jump) vspeed = max(0, 8)
if vspeed > -10 {vspeed = -10}
}

Collision with obj_solid:

if global.grav_switch = 270
{
if vspeed > 0 && !place_free(x,y+vspeed) 
{move_contact(270) vspeed = 0}
}
if global.grav_switch = 90
{
if vspeed < 0 && !place_free(x,y-vspeed) 
{move_contact(90) vspeed = 0}
}

I remember having a engine where you when you jumped, the longer you held the button pressed the higher the player would jump. Now I've searched my entire computer and I can't find it, so I decided to ask here. Is there a good code for such jumping?

Curently using this moving code:

gravity_direction = global.grav_switch
if place_free(x,y+1) {gravity = 0.5} else {gravity = 0}
if keyboard_check(button_left) && place_free(x-3,y) {x-=3}
if keyboard_check(button_right) && place_free(x+3,y) {x+=3}
if keyboard_check_pressed(button_up) && !place_free(x,y+1) {vspeed = -8}
if vspeed > 10 {vspeed = 10}

I'm trying to make a 3D game and I'm trying to make a skybox around the room with night sky textures. But as I'm new to 3D, I still don't quite understand how everything works and I can't seem to be able to make it work. Does anyone know how?

I'm using a texture that's 256x256

Create Event:
skyball = d3d_model_ellipsoid(d3d_model_create(),0,0,0,room_width,
room_height,700,1,2,12);

Draw Event:
d3d_model_draw(skyball,0,0,0,background_get_texture(texture_sky));

I'm trying to make slopes in my game, but there seems to be a problem in the movement code I'm using and I don't know what the problem is. The player gets stuck if it tries to walk up slopes and if you jump up on the slope, you get stuck after just walking a few pixels. This is the code:

if place_free(x,y+1) && !place_meeting(x,y,obj_ladder) {gravity = 0.5} else {gravity = 0}
if keyboard_check(vk_left) && place_free(x-4,y) && ducking = 0 {x-=3}
if keyboard_check(vk_right) && place_free(x+4,y) && ducking = 0 {x+=3}
if keyboard_check_pressed(vk_up) && !place_free(x,y+1) && !place_meeting(x,y,obj_ladder) {vspeed = -8}
if place_meeting(x,y,obj_ladder) && keyboard_check(vk_up) {y-=4}
if place_meeting(x,y,obj_ladder) && keyboard_check(vk_down) {y+=4}
if vspeed > 10 {vspeed = 10}
if place_meeting(x,y,obj_ladder) && !keyboard_check(vk_up) {vspeed = 0}
if place_meeting(x,y,obj_ladder) {vspeed = 0} 
if keyboard_check(vk_right) {if place_meeting(x+1,y,obj_slope_r) {if place_free(x+1,y-1) {x+=3 y-=4}}}
if keyboard_check(vk_left) {if place_meeting(x-1,y,obj_slope_r) {if place_free(x-1,y-1) {x-=3 y-=4}}}

The player mask is 8x16 and the slopes are 16x16.

Please help me find the problem.
