在obj_player里，增加create事件，填写如下代码

//stat
spd=6;
hsp=0;
vsp=0;
jspd=18;//跳跃力度
grv=0.8;//重力
grounded=false;

//moving and jumping
direction=0;
facing_dir=1;//朝向右边，-1为朝向左边

gamepad_set_axis_deadzone(0,0.5);

添加step事件，填写如下代码

//键盘控制代码
//手柄控制代码
var haxis=gamepad_axis_value(0,gp_axislh);
var move_left=keyboard_check(vk_left) or gamepad_button_check(0,gp_padl) or (haxis<0);
var move_right=keyboard_check(vk_right) or gamepad_button_check(0,gp_padr) or (haxis>0);
var jumping=keyboard_check_pressed(ord("Z")) or gamepad_button_check_pressed(0,gp_face1);
var jump_released=keyboard_check_released(ord("Z")) or gamepad_button_check_pressed(0,gp_face1);

//设置移动和速度
var move=move_right-move_left;
hsp=move*spd;//左右速度
vsp=vsp+grv;//向下速度

if move!=0
{
sprite_index=spr_player_walk;
facing_dir=move;
image_xscale=facing_dir;
direction=point_direction(x,y,x+move,y);

}
else
{
sprite_index=spr_player_idle;
}

//jump
if jumping and grounded
{
grounded=false;
vsp=-jspd;
stprite_index=spr_player_jump;
audio_play_sound(snd_jump,1,false);
}

if jump_released
{
vsp*=0.5;
}

//水平碰撞检测
if(place_meeting(x+hsp,y,obj_block))
{
while(not place_meeting(x+sign(hsp),y,obj_block))
{
x+=sign(hsp);
}
hsp=0;
}
x+=hsp;
//垂直碰撞检测
if(place_meeting(x,y+vsp,obj_block))
{
while(not place_meeting(x,y+sign(vsp),obj_block))
{
y+=sign(vsp);
}
vsp=0;
grounded=true;
}
else
{
grounded=false;
}

y+=vsp;

把主角放入房间0，地面绘制好，

这是地面，现在再用建立好的obj_block对象，在地面上再画一层，效果如下

按F5运行游戏，支持手柄控制，效果如下
