collision and selection rts question/problem thingy

[wej42]

ok, im makin an rts game (not dx... im not to good in it yet)
during the code all the people and stuff are Rects
then i "render" the rects that r on the coordinates of where the screen is on the map
now in theory, that would work... im just not 100% on how to do it:
since im drawing everything using transblt on a picture box.. how would i have the prog no when i selected... say a person and which person...

could i do something like (not exact code,just a ruf outline)
on pic_click..()
if mousex and mousey > pics x etc
blah blah... more if its on the coordinates of ne rect
then:
do the stuff
endif
end sub

ok u should get the point, but a few things
1. i think i would have to loop the part where it goes thru and checks if the mouse is on a rect.. cuz i would have to do like
do until i > numOfBuildings
if mousex > blah blah building(i).x then
etc etc stuff
end if

then how would i tell if its being selected.. would i have to make some sort of an index on each thing as i make em?

and i get an error .. i forgot wut it is now (ill post source n **** later) i think it was an overflow when i tried getting the left or right or nething of a rect and comparing it to the mouses... which doesnt make ne sense...

neways, ill post the basic source later

thx in advance
gl on understanding wut i wrote

Use a control array, in the click event use the "index" to know which image is which.

Image1_click(x,...,index)
image(index).left = image(index).left + 1
end sub

that would make the picure you click on move to the left.







Question: How are you doing your unit pathing?

He's using bitblt, not controls... Wej your code should be more like this: If MouseX >= PicRect.Left And MouseX <= PicRect.Right And MouseY >= PicRect.Top And MouseY <= PicRect.Bottom Then MsgBox "It's Selected!!!"

As to the loop, yes, each building (or unit or whatever) should have an index, since they're all in an array. So, huh... what you have there is ok

Good luck on your game
