The program graphs a slop field, basically an approximation of the graph of the antiderivative of the function times any constant (i think)

anyway i ran into a different problem, since the user has to enter the function with x's and y's i created 2 loops that check for x's and y's and change them to z and theta and i changed the for loops and the code inside of them. I brought that to school after testing on basic inputs but when i gave it to the only other decent programmer in the school to show it too he entered 100 and 101 for xmin and 200 and 202 for y min, when he does this the calc only shows an empty graph and then exits the program. the only reason i sould see this happening is that somewhere the graph screen variables change so that max is less than min then it doesnt enter the for loop. and then it resets them to what i want them to be. I'd give you my full code if i knew an easier way to post it but basically....

ask for xmin xmax y min and ymax
loops around if either max is too big
ask for "Resolution of field" not graphscreen res.

hmmm...i see, i was trying to make my code easier to be understood because i usually distribute em around the school. But i guess adding a comment in there would do well in a pinch

i was making a math program for calculus, you basically input an equation for the derivative and the calc will spit out a slope plot (lots of lines aproximating a function with an unknown constant)
anyway the problem is that i set the calc to do 2 for loops so it will hit a bunch of points in a square. but for the inside loop's first iterations before it returns back to the outer loop, the loop starts at zero. then later once it goes in again after it hops out, it executes properly. Another odd thing is that the varialbe starts at the correct value up untill it hits an "expr(str1)" then seems to change to zero when it should start at Ymin (Ymin = -3). The only thing that changes the varialbe is the for loop so im confused as to how this could be happening. I've tried having the loop count up and down but no matter what it starts at zero.
Ex.

CODE

ec1 For (X,Xmin,Xmax,LLen(1)*6 For (Y,Ymin,Ymax,LLen(2)*6 :here Y = -3 (Ymin = -3) expr(Str1) :here Y = 0...wtf? line(X+LLen(1),Y+LLen(2)Ans,X-LLen(1),Y-LLen(2)Ans End End c2

if you would like to know about clarity from someone who is not an ungodly uber BASIC programmer,  i think its fine as well

ya, i figured it out, i changed alot of stuff and set the calibration for like 4 seconds, instead of 1 or 2. The problem misirlou, is that i need to calibrate the program each time it is executed and i don't know how to do it for that code.

ya, i noticed it right after i made the topic, i dont know how to fix it. I'm probably going to work on this after midterms.

I had been thinking about a project to do and i decided i wanted to do a sports game. Then i got the idea of combining sports games with RPG's. Heres what i though:

For example soccer,there would be 4 people on a team. This small field should fit onto half the calc screen without scrolling. you would move the character with the ball like any other rpg character, but when a dfender gets within a few pixels of you it would be like a random battle, there would be 4 ways a person would defend you. if they go from behind you, you have to rapidly  press a button to sprint away, if they challenge from the side you need to press buttons in a circle to do a maradona, if they challenge you from the front you could press buttons in a figure 8 to do a stepover, the person would be infront of you and a little to the side so the stepover would have to take you to the side he isnt, if the person slide tackles you, you would have like a second to press some button to scoop the ball over him and jump. the next section would be passing.

by pressing some button it would start another "random battle type thing except this time instead of a key press you have an aimer (sort of like the field goal aim on madden nfl) and you wold have to aim at your player, if you do it too far behind him then you would loose time, if you did it infront of him a defender might take it, then you would have a power thing, think madden again, if you did too much power the person wouldnt be able to controll it and it would bounce off of his foot, if iit was too easy then a defender could intercept it unless you rapidly pressed some button to have a defender sprint too it. shooting would be another key press thing. first you have like 4 seconds to press the buttons displayed, each button would coorespont to propper shooting technique, the first would be to view the net, the second to look at the ball, the third to get your knee over the ball, the 4th to lock your ankle, the next for medium power, the next for full power and the next for follow through. then a different screen would appear with the goaling in a goal, you have a different aimer(like in a baseball game for hitting the ball) and you have 2 seconds to place the aimer where you want to shoot. from there it would generate the chance you scorred based on shot placement, button press and placement of your player on the field.

anyway that would be the attacking stuff there would also be crossing and heading and volleying and dfending and goalkeeping. but i think you get the gist, oh ya and finnaly when you win a game, your players would gain xp based on thier performance. you would put their pts toward more time to button press, making things easier....

This could happen for any sport, i just thought i'd throw my ideas out there, i am thinking about making the soccer one. i hope this inspires more sports games for the calculator
