Your problem is in your variables. You need some. No integers though, they mess things up something awful. Use only strings. It helps if you put /* at the top of the program and */ at the bottom, I guarantee you will not get a single error.

The real key to effective moving is trigonometry. Using some complicated functions written to inefficiently perform algebra on strings ('cause integers are bad, remember?) you can calculate the projected path of the object to move based on input received from the keyboard (which in itself requires calculation of second derivatives of the input function to detect which keys are NOT pressed.

It's hopeless. You should probably give up now.

What Insectoid means is that you haven't given us any details on what to help you with. We won't write code for you. You need to try to solve the problem yourself (hint: pencil and paper first!) and then arrive at a problem, analyze the problem, try to solve it, etc.

If you run into a specific problem that you can't seem to solve, then ask for help.

If you want to look at tutorials, try the Turing Tutorials section.

sorry when i posted it some how erased when i sent it.

[william 01]

i tryed to post atachments but they wont let me post more than one.

[Insectoid]

This line has a syntax error in it:

code:

if chars (KEY_UP_ARROW) and y1 < maxy - 25 and whwhatdotcolorx1, y1 - 10) = black then

Anyway, you're doing it right so far. You're just missing the important bit where we actually update the position (x1, y1). Just before you draw everything (or just after, your choice) but inside the main loop, you need to add

code:

x1 += vx y1 += vy

You'll also need to add gravity to do jumping, so in the loop you need to check if the character (mario I assume in this case) is standing on something, and if not, subtract N from vy (N being whatever you set your gravity to).

Also, you need to call your 'movement' procedure somewhere in the main loop you need to have.

[william 01]

in my case how would i put in gravity

[TheGuardian001]

Keep on moving the character (And everything else that gravity will effect) down. So just have a certain amount subtracted from the character's y coordinate (or from y velocity, as long as you do it before subtracting y velocity from y coordinate) every time the main loop runs.

explan please

[USEC_OFFICER]

It's very easy.

Y is the y-coordinate of the character. i.e. Up-down.

By subtacting a set number from Y, the character will move down, simulating gravity.

If you have a varible that replaces the set number, you can change the strength of the gravity.

insectoid could you post example?

ps every one thank you for your help but "mario" still won't move.

code:

x1+=vx vy -= gravity y1+=vy

Done.
