Just use this:

if player.x == enemy.x then
FireBullet()
end
if bullet.y > player.y then
bullet.y = bullet.y - 4
end


This will make it, so when you fire the bullet, it will come straight down. And it will only fire if the player is directly under the enemy.

[jamz1825]

ok i guess that will work thnx

[Glynnder]

i see what you are doing!

easy, as long asyour player saysy at the same 'y' location, just make its x loaction be called bulletdestination then make thhe bullets go to there

[Access_Denied]

You can also make it a little more tolerant. Like it the player is sort of under it. Like this:
if (player.x + 10) == enemy.x then
FireBullet()
end
if (player.x - 10) == enemy.x then
FireBullet()
end
This will make it so if the player is kind of under the enemy, it will fire. You can also change the speed of the bullet from 4 to something faster.

Yeah but you don't want the bullet to follow the player. Bullets go in straight lines not loops and zigzags.

How can I make the text from Image2 go into Image1??? Images were borrowed from ProgramLua to show an example...

**Image1**

**Image2**

[Access_Denied]

Well image 2 is transparent, so just paste 2 on top of 1. Like this:

screen:blit(0,0,image1)
screen:blit(0,0,image2)

[Dr.Gringo]

Thanks ARza, sorry for using ur images without asking u...

[xploren]

Thanks ARza, sorry for using yours and Appleseed629's images without asking u...

Corrected :).

It's cool, you weren't really using them. Only for an example.

[xploren]

How do I make the player move if the player moves the analog stick in Lua?

[SG57]

You know you dont know the concept when you always use game specifics when asking for help ;)

You should be asking how to manipulate a variable, using hte analog stick...

I havent used LUA in forever, so i dont know the control name for the analog stick, but it ranges from -128 - +128, so say if pad:analogX() > 50 then increase_x_co-ordinate...

[Dr.Gringo]

Once you have blitted a text image how do you change to another??? Is it going to overlap or would it just substitute...

[xploren]

LOL, Yeah sure Appleseed629

I assume you don't know that ARza and I made it together? Look in the credits.

It's actually from -127 to 128. -128 will give you an error.

lol, ouch no recognition.
and its analog_x methinks

Tell me about it. Every person who thinks ProgramLua is great knows that I did half of the work. Except Dr. Gringo.

And... hey, Glynnder, you keep changing your sig. Maybe I should make one for ya? That'll be 500 poitns please. Lol!

As most of you probably know, I'm making a game where you draw designs. I have the drawing part done. When you press X on a square, it turns it black. O turns it white. Well, when trying it on my PSP it runs horribly slow. I am using PSPmillionaire's scrolling tile engine. I modified it to work. But when it's on a PSP is runs slow. I've tried .16 and .20. I even tried the .20 mod by Cools and set the CPU to 333 and it still runs slow. Here's my code, any suggestions?

Once you have blitted a text image how do you change to another??? Is it going to overlap or would it just substitute...

I did know that Appleseed629 did half of programlua however i said arza because he was on the above post, rofl

[Grimfate126]

Once you have blitted a text image how do you change to another??? Is it going to overlap or would it just substitute...

why did you post the same question twice?? anyway, what do you mean by "text image"?? like an image with text on it?? it so, just clear the screen, and blit the next image. OR, keep the background image the same, and just substitue the text.

[Access_Denied]

I did this:

current = 1
image = {}
image[1] = "image.png"
image[2] = "image.png"
image[3] = "image.png"
image[4] = "image.png"
current_image = nil
current_image = Image.load(image[current])

Understand? If you change the variable "current" the image will change.

I did know that Appleseed629 did half of programlua however i said arza because he was on the above post, rofl

Then why did you say, "Sure, Appleseed629." That I wonder...

ProgramLua is like that: it changes to another image when you press a button. If you want two images at the same time, you're gonan have to move the second by 1 more in the x/y coordinate.

[Dr.Gringo]

Arza if i do it your method would i have to Load all the images at the beginning of my script

[Grimfate126]

Arza if i do it your method would i have to Load all the images at the beginning of my script

not necessaliry. but you have to load them before yu use them.

and try not to load them in your while true do loop, thats make your game VERY VERY slow.

[Dr.Gringo]

When I clear the screen how can i keep my background and only change the picture with the text.

Example:

oldpad = Controls.read()
while true do
pad=Controls.read()
screen:clear()
screen:blit(0, 0, clear, false)

if pad:down() and oldpad:down() ~= pad:down() and current = 20 then
pictext = Image.load("images/pictext.png")
screen:blit(0, 0, pictext, false)
end

screen.waitVblankStart()
oldpad = pad
screen.flip()

Example:

oldpad = Controls.read()
while true do
pad=Controls.read()
screen:clear()
screen:blit(0, 0, clear, false)

if pad:down() and oldpad:down() ~= pad:down() and current = 20 then
pictext = Image.load("images/pictext.png")
screen:blit(0, 0, pictext, false)
end

screen.waitVblankStart()
oldpad = pad
screen.flip()

actually, ur gonna have to make an array:

text = {}
text[1] = Image.load("yourtextimagename")
-- etc.
currentText = 0

oldpad = Controls.read()

while true do

pad=Controls.read()
screen:clear()
screen:blit(0, 0, clear, false)

if currentText ~= 0 then
screen:blit(0, 0, text[currentText])
end


if pad:down() and oldpad:down() ~= pad:down() and current = 20 then
currentText = 1
end

screen.waitVblankStart()
oldpad = pad
screen.flip()
end

what's wrong with this one

red = Color.new(255,0,0)
black = Color.new(0,0,0)
white = Color.new(255,255,255)

menustatus = 1

while true do
screen:clear(black)
pad = Controls.read()

if pad:up() then
menustatus = menustatus - 1
screen.waitVblankStart(4)   
end

if pad:down() then
menustatus = menustatus + 1
screen.waitVblankStart(4)   
end

color={white, white, white}
while true do
screen:print(50, 50, "Play", color[1])
screen:print(50,60,"Options", color[2])
screen:print(50,70,"Exit", color[3])
end
color[menustatus]=red

if menustatus == 1 then
    if pad:cross() then
    screen:clear()
    screen:print(50, 50, "Play", color[1])
    end
end

if menustatus == 2 then
    if pad:cross() then
    screen:clear()
    screen:print(50, 50, "Play", color[1])
    end
end

if menustatus == 3 then
    if pad:cross() then
    break
    end
end

if menustatus <= 0 then
    menustatus = 3
    end

if menustatus => 4 then
   menustatus = 1
   end

screen.flip()
screen.waitVblankStart()
end

You have two 'While true do' loops

Working on a game. Here's my code.

Code thats a problem -

EnemyList = {1,2,3,4,5,6}
       
      (REST OF CODE)

      if Enemy[EnemyList[target]].health <= 0 then
         Enemy[EnemyList[target]].state = "dead"
      end

      if Enemy[EnemyList[Length]].state = "dead" then
         screen:print(10, 130, "You killed all the enemies")
      end

Example of my table -

Enemy = {}
Enemy[1] = {name = "Zombie", damage = 3, health = 15, combatx = 300, combaty = 5, image = mzombie, state = "living"}
Enemy[2] = {name = "Zombie", damage = 3, health = 20, combatx = 310, combaty = 15, image = mzombie2, state = "living"}

The error I get is " 'then' expected near '=' "

I probably didn't need to include all that information, but more is better then less. This is probably an easy solution also, but I don't care b/c im tired.

you need two '=' to compare:

EnemyList = {1,2,3,4,5,6}
       
      (REST OF CODE)

      if Enemy[EnemyList[target]].health <= 0 then
         Enemy[EnemyList[target]].state = "dead"
      end

      if Enemy[EnemyList[Length]].state == "dead" then
         screen:print(10, 130, "You killed all the enemies")
      end

Example of my table -

Enemy = {}
Enemy[1] = {name = "Zombie", damage = 3, health = 15, combatx = 300, combaty = 5, image = mzombie, state = "living"}
Enemy[2] = {name = "Zombie", damage = 3, health = 20, combatx = 310, combaty = 15, image = mzombie2, state = "living"}
