| i made a menu for my game, right now, its only start & quit. when you click on the one that is listed in the program first, its fint, but for the one that is checked secons, you have to click on the exact sreen coordnates. this is what it is If ImagesOverlap(cross,MouseX(),MouseY(),start,512,300) And MouseHit (1) Then game() EndIf If ImagesOverlap(cross,MouseX(),MouseY(),quit,512,700) And MouseHit (1) Then End EndIf "i don't know how to do that thing where the code is black & green" |

| example: start works when you click on the image quit works when you click on the exact position of the image (512,700) instead of the whole image. HELP PLEASE |

| based on the code you have posted, if it appears exactly like that, the only logical explanation is that quit is a 1x1 pixel image OR that you have made a mistake somewhere else in code you haven't posted. Also I would read the state of the mouse hit into a variable at the start so the mousehit function doesn't clear the input buffer when first tested. Then use the variable to check the state of the button in each IF statement. You could also use Else between each If statement to clarify things but you'll end up with a lot of indenting, to be honest I don't always bother either. I never thought of doing ImagesOverlap, makes sense, I always read in the mouseX and Y into two variables (mx, my)at the start of each frame and then do: If mx >= menux and mx < menux + imagewidth(menu) and my >=menuy and my < menuy + imageheight(menu) then same thing really. It's possible "quit" isn't the correct variable name I guess too, although I don't know (without testing) if ImagesOverlap would crash if given a null image (variable = 0). |

| I'm sure his problem is the double usage of the MouseHit command. |
| ||
| yeah the double use of the mousehit command is not a good thing but as for why only on one pixel, that's weird, unless he's misreporting by accident. |
| ||
| ok , im sounding really dumb, but how do you put the mousex() and mousey() into a variable? |
| ||
| mx=MouseX() |
| ||
| o, ok hehehehe |
| ||
| Hmm... I've run into similar problems with mousehit, while mousedown seems to do the trick, and for a noobie like me, I'm stumped. |

| You have to place the MouseHit() command into a variable if you intend on performing checks on it every time. Remember, the ????Hit() commands clear their buffers once you use them even once. in my programming tutorial, I comment on this in several of my example programs like so: ;Collect user input upkey = KeyDown(200) ;up arrow ;It's a good practice to collect these inputs only once downkey = KeyDown(208) ;down arrow ; per loop. This will prevent odd behaviors from happening, leftkey = KeyDown(203) ;left arrow ; for instance if the state of a key changes between multiple rightkey = KeyDown(205) ;right arrow ; checks of that key while still in the same loop. jumpkey = KeyDown(57) ;spacebar fastkey = KeyDown(42) ;left shift key If rightkey ;Check if the right key is being pressed If fastkey ;Check if the fast key is also being pressed xmove = 8 ; if so, then attempt to move 8 pixels Else xmove = 4 ; if not, then only attempt to move 4 pixels EndIf EndIf If leftkey ;Check if the left key is being pressed If fastkey ;Check if the fast key is also being pressed xmove = -8 ; if so, then attempt to move -8 pixels Else xmove = -4 ; if not, then only attempt to move -4 pixels EndIf EndIfNotice that I checked the fast key twice? This works because my variable will not change its value between my If statements. However, if I had checked the key directly, the user could have let go of the fast key between my two If statements. |
