Getting the Length and Width of a Random Rectangle

[_dementia_]

Hello! Been a while but I'm finally coding my 2nd 'game' in love and I've gotten a bit stuck.

I have some randomly sized rectangles that I need to get the width and length of to determine if there's a collision to do.

Here is my enemy_load() function

Code: Select all

  enemy = {}
  enemy.x1=0
  enemy.x2=love.graphics.getWidth()
  enemy.y1=0
  enemy.y2=love.graphics.getHeight()
  enemy.minSize1=15
  enemy.minSize2=enemy.minSize1*2
  enemy.maxSize1=30
  enemy.maxSize2=enemy.maxSize1*2
  enemy.initspeed=20
  enemy.timer_init=1
  enemy.timer=enemy.timer_init
  
  function enemy_spawn(x,y,width,height,speed,r,g,b)
    table.insert(enemy, {x=x,y=y,width=width,height=height,speed=speed,r=r,g=g,b=b})
  end

As you can see, there is no enemy.length or enemy.width. I later use an ipairs loop to get the v.width and v.height of the rectangle.

When A timer comes up, this runs:

Code: Select all

    enemy_spawn(math.random(e.x1,e.x2),math.random(e.y1,e.y2),math.random(e.minSize1,e.minSize2),math.random(     e.maxSize1,e.maxSize2),enemy.initspeed,math.random(0,255),math.random(0,255),math.random(0,255))

It makes sense in context, although I'm sure I'm going about it the hard way. Every variable of the rectangle is randomized including x,y,length and width. Length and width should have been inserted with the enemy_spawn() function, right? Well it's not, apparently. Because when I run this:

Code: Select all

for i,v in ipairs(enemy) do
 for bi,bv in ipairs(bullet) do
  if bv.x > v.x+v.width or bv.x < bv.width-bv.w or bv.y < v.y+v.height or bv.y > v.height-v.height then
 end
 end

it gives me this when a bullet comes out:

Which means that it's not creating a width or height variable and I'm quite lost on it. I don't see a way to do like love.graphics.getWidth() for rectangles and I don't know how to do it myself if it won't insert the way I'm doing it.

I'm probably missing something obvious!

I should warn that my code is a warzone of uncommented, unorganized scrap. I'm simply doing a crummy game to learn things for better things. Hopefully that doesn't stop one of you smart people from helping me out!

Cheers!

Edit: I commeted out my bugged collision code. Here is a version of the game that's "playable." You should see what's up.

Right now 1,2 and 3 change the RGB colors of the character and the bullets it fires. The goal is that you have to get your RGB colors close to the enemy's RGB colors(which are completely random at spawn) and it will kill them/make them lose health.
Also the border has a threshold like that already, if your RGBs are more than 40 units away, it will make the walls grow, if you're within 40, it'll make them grow. Still have to polish how it works, but right now it's just testing an idea I have.
Doesn't really play well but it's the best I've done so far.

The problem is with bv.width not v.width.

Here's a little bit more about the error with a collision system I used in another game of mine that should work well with the rectangles of this game...But this picture demonstrates why I think it's the enemy's v.width and not the bullet's bv.width

See for yourself and separate your if condition so v.width and bv.width are on different lines, it will pop an error on line with bv.width.

The other unrelated error you just posted is because you have a typo there, see obj2 vs ob2.

And if i'm understanding that code bit right, you also have obj1 vs ob1 in the line under; that would probably error as well...as well as the ones on the two lines after; you really should name your variables a bit less confusingly

I'm really realizing this with this game. I have plans to help me out a lot in the next game, but this one isn't worth a full rewrite full of features I don't yet know exactly how to program. This is a huge upgrade from my last game in terms of complexity and whatnot. I'm just wanting to get it working, get some feedback and make Every Other Game is Inferior 3 my best shitty work yet

Thank you for your help! I've managed to get it all stable. Still a long way to go. I'm postng an exe because that's what I have ready. If you want a .love, just yell at me!
