dx collisions

[Wisin]

Hi, i would like to know if theres a way to check if a dx image is collisioning with another dx element, example another image, thanks.

For that, everything has to be mixed in one resource. Create an object "dximage" or somewhat, and then in onClientRender, when rendering these, check if they collide and trigger an event if they do. That's all

[botanist]

But Orange, there are no functions for that. So he will have to do calculations with the positions + size, and when the second dx position is less then the previous result, they will collide. Eg:

dx1 starts at x=40, and is 60 wide. dx2 starts at 90. 40+60=100, so dx2 will collide. But what if dx2 starts at x=10? Then do it vice versa; dx2 will be calculated as dx1.

[Orange]

I've just written how to start :> Of course, calculations are needed, and dx objects are one of the most useful solutions right now.

should work, didn't test it tough.

  
function doesCollide(x1,y1,v1,h1,x2,y2,v2,h2) 
  local horizontal=(x1)~=(x1+v1) or (x1>x2)~=(x1>x2+v2) 
  local vertical=(y1)~=(y1+h1) or (y1>y2)~=(y1>y2+h2) 
  return (horizontal and vertical) 
end

Thanks karlis, but im not sure of how to use your function, i want to check when my character (a dx image) collides with a enemie (another dx image) and then do something (thats for later).

Thanks karlis, but im not sure of how to use your function, i want to check when my character (a dx image) collides with a enemie (another dx image) and then do something (thats for later).

np

first 2args is x and y cord of 1st element, then its width, then height, then same 4 for second.

returns true/false

however you should test it fully as well, i cant gurantee itll work.

[Wisin]

wow, thank you !! it works perfect!

[karlis]

np

[Wisin]

i have another question, is possible to check if the "character" is over "enemie" head?

[karlis]

you need to define how big is head's dimensions and call func with that.

[Wisin]

im not sure of understand correctly, what do you mean?

[karlis]

find the cords where the head is located, and call func with them.

[Wisin]

i have another question, is there a way to check if im over another DX element (a image)? im making platform mini game that requires this, if someone could tell me i would appreciate it.

[qaisjp]

Are you making "Mario returns to San Andreas!" game?

[Wisin]

no, is not "Mario", is another kind of game.

[Orange]

Huh, I remember that I was creating a game like that for my race server :> People could play mario on a "psp" ingame

Lol, offtopicers See The-kid's IWTG gamemode, that's a pretty nice 2d mode.

Wishin: when 'over'? You mean with your mouse? If so, let me make some simple functions which you can expand.

[Castillo]

Remi-X, I think he want's to check whenver is his character image over another static image or something like that.

[botanist]

In that case he just asks the same question again, as karlis already posted a script for him to do such.
