GameMaker Collision工作速度太快

在編程方面，我有些初學者，最近我在GameMaker Studio：Professional中爲一個學校項目編寫了一個遊戲代碼，並且遇到了一個小問題玩家在另一個敵人之上登陸。因爲現在我的玩家在足夠高的速度下不會註冊登陸並摧毀敵人的實例，而只是受到傷害（或者遊戲將會重啓，因爲我還沒有實現該部分）。已經測試了一些東西，似乎以更高的速度玩家跳過它可以摧毀敵人的範圍，而是傳遞到敵人附近受到傷害，儘管在低速時玩家只與敵人發生碰撞精細。玩家在可變高度跳轉，這個高度由他們持有空格鍵的時間量來控制。我相信這可能是由於我的重力價值，因爲它不是一個整數，但我不確定。我也嘗試給玩家添加一個終極速度，但是我嘗試過的仍然保持相同遊戲審美的數字並沒有解決這個問題。GameMaker Collision工作速度太快

這裏是我的兩個選手對象與敵方目標代碼： Player對象：

Create Event: 
execute code: 

hsp = 0 
vsp = 0 
grav = 1.5 
movespeed = 8 
move = 0 
jumpsmax = 2 
jumps = 0 
jumpspeed = 18 
dir = 0 

Step Event: 

execute code: 

//Movement 
//Main controls 
key_right = keyboard_check(ord("D")); 
key_left = keyboard_check(ord("A")) * -1; 
key_jump = keyboard_check_pressed(vk_space); 
key_jump_held = keyboard_check(vk_space); 

move = key_left + key_right; 
hsp = move * movespeed; 
vsp += grav; 

if (place_meeting(x,y+1,obj_wall)) 
{ 
    jumps = jumpsmax; 
} 

if (keyboard_check(vk_down) != 1) 
{ 
    if (key_jump) && (jumps > 0) 
    { 
     jumps -= 1; 
     vsp = -jumpspeed; 
    } 
} 

if (vsp < 0) && (!key_jump_held) vsp = max(vsp,-jumpspeed/3) 

//Horizontal Collision 
if (place_meeting(x+hsp,y,obj_wall)) 
{ 
    while(!place_meeting(x+sign(hsp),y,obj_wall)) 
    { 
     x += sign(hsp); 
    }

    vsp = 0;

y += vsp; 
//Shooting 
key_k = keyboard_check_pressed(ord("K")) 
if (key_k > 0) 
{ 
    bullet = instance_create(x+5*move,y,obj_pellet);

//Bullet Collision

restart = keyboard_check(ord("R"))

敵方目標：

execute code: 

dir = 1; 
hsp = 0; 
vsp = 0; 
grav = 0.8;

Step Event: 

execute code: 

hsp = dir * movespeed;

image_xscale = dir * -1; 
//Horizontal Collision 
if (place_meeting(x+hsp,y,obj_wall)) 
{ 
    while(!place_meeting(x+sign(hsp),y,obj_wall)) 
    { 
     x += sign(hsp); 
    } 
    hsp = 0; 
    dir *= -1; 
} 
x += hsp; 

//Vertical Collision 
if (place_meeting(x,y+vsp,obj_wall)) 
{ 
    while(!place_meeting(x,y+sign(vsp),obj_wall)) 
    { 
     y += sign(vsp); 
    } 
    vsp = 0; 
} 
y += vsp; 

//Enemy Collison 
if (place_meeting(x,y,obj_player)) 
{ 
    if (obj_player.y < y-16) 
    { 
     with (obj_player) vsp = -jumpspeed; 
     instance_destroy(); 
    } 
    else 
    { 
     game_restart(); 
    } 
} 
if (place_meeting(x,y,obj_pellet)) 
{ 
    with (obj_pellet) 
    { 
     if (place_meeting(x,y,obj_enemy)) 
      { 
       instance_destroy(); 
      } 
    } 
instance_destroy(); 
} 
if (place_meeting(x,y,obj_badpellet)) 
{ 
    with (obj_badpellet) 
    { 
     if (place_meeting(x,y,obj_enemy)) 
      { 
       instance_destroy(); 
      } 
    } 
instance_destroy(); 
}

看起來你的問題是，當玩家擊中敵人，它登錄到頂端太過分了。

這很難給你一個答案，這將涵蓋所有可能發生的，但一個簡單的解決方法是：

if (obj_player.vsp > 0 and obj_player.y - obj_player.vsp < y-16) 
{ 
    with (obj_player) vsp = -jumpspeed; 
    instance_destroy(); 
}

什麼，我這裏做的是檢查玩家正在下降，然後檢查，如果玩家是在上一步（即發生碰撞之前）的敵人之上。這將區分從上方墜入敵人並從側面進入。
