I made a map with presses in it. When I enter the map, all of the presses fall at once without me going under them.
How can I fix this?

I took a gander and it's fully able to shoot up and down, but it never actually runs a check to see if you're above/below it.

aha, right here:

:down_check_end
mov eax, PlayerXpos
cmp npc.x, eax
jl :player_is_left
mov npc.direction, 0
jmp :dir_air_end
:player_is_left
mov npc.direction, 2
:dir_air_end
mov eax, npc.direction
mov shootvar, eax

shootvar dictates the direction the shots are fired.
Just build a check to see if quote is so close and so high above the NPC and make shootvar 1 in that case.
Easy

(Good thing I think ahead in ever piece of code I write incase I want to go back and expand upon it)

E: also because you removed the fake death sequence, you're need to adjust some of the npc.scriptstate variables or else the game will crash...
E2: You'll have to also change around the render system/sprites to make it look up when you want it to...

 

Uhm. Hi there. Can someone help me? How to increase shooting speed for first level Machine Gun? I know how to work with assembly, but i don't know adress for first level Machine Gun...

Hello. I need some help replacing the icon of Cave Story's .EXE file.
I keep trying with Resource Hacker, but to no avail. Could someone explain to me how I should do it?

 

So you've edited the icon files and saved it using resource hacker? That should do the trick. I've noticed that sometimes when I try and change an executable's icon it doesn't update properly, it just shows the original instead (I use WIndows 7, and it's also happened with Vista). I believe in that situation it's just on your side. I think you can confirm if the icon did change properly if you copy-paste the executable to a different location and see if the icon changed.

 

I keep trying, I even rebooted my system to see if it worked, but of course it didn't. Do you know a way around this? I tried what you suggested, but that didn't work either. Dang. Also, I'm using Windows 8.

 

Same problem with me, only solution I've found is to change the folder's name.

 

I believe these are the resources you want to edit in order to change the icon of the executable. I just want to confirm that this is what you're editing, because that's all you need to do to change the icon, as far as I know.

 

How did you change the Icon? Did you just replace it or did you add a new icon?
If you replaced it, it might be a good idea to just wait it out for a while.

 

Ughh... This is difficult. The Icon Group folder only contains the icons themselves, not two folders in which contain their respective icon. I'm very confused.
