Is there a way I can set the direction of an NPC like left or right?

Is there a way I can set the direction of an NPC like left or right?

NPC.direction = (-1 for left, 1 for right)

How do I change the projectile that an NPC throws. You could do something like that easily in LunaDLL.

The easy and lazy way to turn all NPC A into NPC B is:

Code: Select all

function onTick()
	local transform = NPC.get(npcID, section)
	for k,v in pairs(transform) do
		v.id = otherNPCID
	end
end

This was my code:

Code: Select all

function onTick()
   local transform = NPC.get(87, 1)
   for k,v in pairs(transform) do
      v.id = 1
   end
end

I tried to make Bowser shoot Goombas instead of flames but he still shoots flames.

Change the 1 to -1.

(That's the first 1 he's talking about btw)

Thanks dude, it now works. Now I made Bowser shoot Rinkas. Has anyone done that?
Update = How do you fix the fact that the sprites look wrong when they are thrown as a replacement?
And how can you make SMB1 Bowser not shoot flames at all? When I set NPC-87 replacement to 0 the flame appears for only a split-second.

You might want to mess around with the Bowser AI.

Out of curiousity, has anyone made Horizontal moving Thwomps, or the ability to have Diagonal projectiles (Aka Mario 3 Cannons)? If not, where should I start about trying to code these myself?

Rednaxela used horizontal-moving "Maverick" Thwomps in a MaGLx2 level. Diagonal projectiles are much simpler and only involve making the values for NPC.speedX and NPC.speedY have the same absolute values

What is the undocumented glDraw argument "sceneCoords" and how do I use it?

"sceneCoords = true" will set the coordinates for the verteces to be scene coordinates, rather than screen coordinates.

Is that possible to make the player fly (with leaf, tanooki, etc (not a blue shoe lol)) without limit? (aka Infinite flying)

[TheUNICORNTrap]

Hey I need to know if I can install this game for the mac. I am a new player and am interested in starting this out.

PLEASE reply thank you.

This page has some helpful memory addresses. Scroll down to flight related adresses.

You can use "Flight time remaining" to make sure that it does not count down while you are flying. Set it with Player:mem() http://www.wohlsoft.ru/pgewiki/Player_(class)

You probably want to check for "isFlying" first, and if true, set the "flight time remaining" to a certain value.

So ehm, anyone here knows how to make a code that there is red fog that becomes less transparent each time the player walks one screen further?

You will have two x coordinates in your level. The first one for when you want to start drawing fog, and the second one for when you want your fog to reach full opacity. (let's call them A and B)

So, you want to take the player's x (player.x) coordinate, or the player camera's x coordinate ( Camera.get()[1]x+Camera.get(){1].width ) and check if they are within your points A and B.

If you draw a single fog image, you can use Graphics.drawImageWP and set your opacity depending on the x coordinate difference of the player and point A/B.

If you want to use fog particles, look for: http://wohlsoft.ru/pgewiki/Particles.lua

Okay, I've loaded the Level Timer API into my level but the new UI graphics don't appear. I've tried putting those graphics into my level's folder but nothing happened.

Have you actually set the timer using setSecondsLeft() and setTimerState() ?
