----------------------------------- yusong Fri Jan 11, 2008 3:25 pm Pictures ----------------------------------- I am making a game and there is one part where depending on the element that the player picks, a different coloured orb is drawn. So it would be like this if your element was Fire Pic.Draw (FireOrb, CharX, CharY, picCopy) But what if the element was say, water, but i dont want to do Pic.Draw (WaterOrb, CharX, CharY, picCopy) Is there a way to do something like this? Pic.Draw (Element + Orb, CharX, CharY, picCopy) ----------------------------------- Tony Fri Jan 11, 2008 4:00 pm RE:Pictures ----------------------------------- not quite in this way. That's a variable pointing to the picture, so instead of just fireOrb := Pic.New() waterOrb := Pic.New() you should also have something like elementOrb := fireOrb and then you can always Pic.Draw(elementOrb), and later change what that particular element variable points to. ----------------------------------- yusong Fri Jan 11, 2008 5:02 pm RE:Pictures ----------------------------------- kk, thank you for the help. ----------------------------------- yusong Fri Jan 11, 2008 5:06 pm RE:Pictures ----------------------------------- Also, I would like this orb to move to the point I click on the map, how would I do that? ----------------------------------- Sean Fri Jan 11, 2008 5:08 pm Re: Pictures ----------------------------------- Are you saying, redraw the picture there? ----------------------------------- Tony Fri Jan 11, 2008 5:12 pm RE:Pictures ----------------------------------- Pic.Draw (Element + Orb, CharX, CharY, picCopy) set your CharX and CharY to the location of the mouse. You can get the coordinates of the latter with Mouse.Where() ----------------------------------- shakin cookie Fri Jan 11, 2008 5:13 pm RE:Pictures ----------------------------------- also, you could PicMerge the element colour and the orb, or use turing's new picBlend Pic.DrawSpecial(200,100,picCopy,picBlend,100) ----------------------------------- Sean Fri Jan 11, 2008 5:17 pm Re: Pictures ----------------------------------- Yes, use mouse_x, mouse_y then if button is pressed, clear screen and redraw orb where mouse_x is. ----------------------------------- yusong Fri Jan 11, 2008 5:29 pm RE:Pictures ----------------------------------- No, I mean moving it across the screen, as in like a magic spell moving across the screen. Sry for the confusion. ----------------------------------- Tony Fri Jan 11, 2008 5:48 pm RE:Pictures ----------------------------------- use a for-loop ----------------------------------- yusong Fri Jan 11, 2008 5:49 pm RE:Pictures ----------------------------------- What do you mean? ----------------------------------- Nick Fri Jan 11, 2008 6:53 pm RE:Pictures ----------------------------------- for x:orbx.. mousex orbx:=mousex end for Tony wouldn't it be better to rather increase the orb x and y each run through the main loop to make it look cleaner? ----------------------------------- yusong Fri Jan 11, 2008 7:38 pm RE:Pictures ----------------------------------- So... How do i do say, from one point to another, that is not on a line or diagonal? ----------------------------------- Nick Fri Jan 11, 2008 7:41 pm RE:Pictures ----------------------------------- hmmm I'll see if I can find some old code that you can learn from EDIT: found some process moveGuy1 if chara (1) = true then anox := x%this is old code I'm sorry for the anoy := y%poor structure and x and y are mouse location loop %also you probably don't want a process sso try to switch into a procedure if anox > movex then movex := movex + 1 elsif anox < movex then movex := movex - 1 end if if anoy > movey then movey := movey + 1 elsif anoy < movey then movey := movey - 1 end if exit when movex = anox and movey = anoy %delay (2) end loop end if onlyOnce := false end moveGuy1 also please note I no longer write like this and cannot believe I ever had :S ----------------------------------- yusong Fri Jan 11, 2008 8:13 pm RE:Pictures ----------------------------------- kk, THX but, it is a 2D Tile game, so, whenever I click, it just stops and the pic does not show. how do i stop that? ----------------------------------- Nick Fri Jan 11, 2008 8:22 pm RE:Pictures ----------------------------------- the only things I can think of are you are stuck in a loop somewhere and cannot get out or you may have forgot a View.Update ----------------------------------- yusong Sun Jan 13, 2008 5:12 pm RE:Pictures ----------------------------------- Instead of the one momop suggested, wouldn't the equation of a line work too? Y = (Point1 Y - Point2 Y) / (Point1 X - Point2 X) * X - Point2 X + Point2 Y ----------------------------------- Saad Sun Jan 13, 2008 6:14 pm RE:Pictures ----------------------------------- Might I suggest using trig, rather then the equation of a line. Also you probably are stuck in a loop. ----------------------------------- yusong Sun Jan 13, 2008 6:49 pm RE:Pictures ----------------------------------- Oh, Ok, Thanks Guys. ----------------------------------- yusong Sun Jan 13, 2008 7:15 pm RE:Pictures ----------------------------------- kk, so i tried the line equation thing, it sort of works, but i am still stuck in a loop. My code goes like this: if Clicked then loop NewY := ceil ((CharY - MY) / (CharX - MX) * (CharX + NewX) - MX + MY) Pic.Draw (ElementalOrb, NewY, NewX, picMerge) exit when NewX = MX and NewY = MY if MX > CharX then NewX += 1 elsif MX < CharX then NewX -= 1 end if end loop end if So, if you click somewhere it draws the thing, but how do i get out of the loop, cause everytime i click, it jusst stops. ----------------------------------- Nick Sun Jan 13, 2008 8:03 pm RE:Pictures ----------------------------------- make clicked a boolean varible if mouse button clicked then clicked = true and MX and MY = mx and my then get rid of the loop and make exit when into a if [condition] then clicked = flase ----------------------------------- yusong Sun Jan 13, 2008 8:50 pm RE:Pictures ----------------------------------- Wait, what? So, get rid of the loop, okay. Clicked is a boolean variable. And make 2 new vaiables called mx and my, so when mouse is clicked, mx=MX and my=MY. get rid of exit when and make it and if statement, so, if Cilicked = false then exit out of the main loop. Did i get that right? ----------------------------------- yusong Mon Jan 14, 2008 8:57 pm RE:Pictures ----------------------------------- Ok, Saad, I haven't studied Trig yet, I think I am doing it next year, so, would you plz explain it to me? ----------------------------------- Saad Mon Jan 14, 2008 9:05 pm RE:Pictures ----------------------------------- Although it was a side point, trig is basically a set of ratios in a triangle relating to angles, I suggest [url=http://www.clarku.edu/~djoyce/trig/]this as a good tutorial. Also trig is taught it grade 10 ;) ----------------------------------- yusong Fri Feb 01, 2008 3:45 pm RE:Pictures ----------------------------------- KK, so I got it to work with the equation of a line cause I am too noob to use Trig yet, but now, the projectile flickers and if you move the guy while you shoot, the crashes, any suggestions guys? ----------------------------------- Nick Fri Feb 01, 2008 3:51 pm RE:Pictures ----------------------------------- 1) do not use processes 2) only use a single View.Update 3) could you post the error message? ----------------------------------- yusong Fri Feb 01, 2008 4:10 pm RE:Pictures ----------------------------------- NVM, I fixed the error part, but, and took out the extra View.Update, but now when I move, and shoot, the projectile curves and doesnot go straight, any way to fix that and add multiple projectiles? ----------------------------------- A.J Fri Feb 01, 2008 5:06 pm Re: Pictures ----------------------------------- just make sure you keep redrawing the picture (show me your code and i'll see what's wrong with it)
