I think it's time to collect them all again :lol:

later I can gather them and store them into one nice post

me starts off with:

---

Kill "Done"
Kill the pesky "Done" at the end of your BASIC program by entering the following code as last line:
c1-->

CODE

ec1:Output(1,1,"c2

ec2

---

-=removed, the px function is well documented in the manual last time I checked=-

---

Using Complex numbers
Utilizing complex numbers to minimize variable usage:
Complex numbers have the following properties:

-Positivity/Negativity or real number (boolean)
-Integer part of real number
-Decimal part of real number
-Positivity/Negativity of imaginary number (boolean)
-Integer part of imaginary number
-Decimal part of imaginary number

commands to get these values:
-real( (ok, xLib may interfere with this, so this is unusable while also using xLib)
-imag(
-iPart(
-fPart(

using these properties of complex variables in the right way can substitute the usage of six real variables!

c1-->

CODE

That is all that needs to be said.

we need to repost them here as well, maybe I could find some tricks in the google cache

Erasing 'Done' is easier with c1-->

CODE

ec1"c2

ec2

xLIB Check
c1-->

CODE

ec11
real(0
If not(Ans:Then
Pause "xLib Needed
Stop
Endc2

ec2

Will check to see if xLIB is installed or not. We had it before and I think this is the most optimized version...

White lines using "Line("
c1

-->

CODE

ec1Line(x1,y1,x2,y2,0c2

ec2
Credit to CDI, I picked this trick up from ADotRPG...

the line one is in the book too I belive

DJ Omnimaga · « **Reply #7 on:** April 28, 2006, 10:22:00 am »

white lines too I think, at least the old ti manual for 83+

Radical Pi · « **Reply #8 on:** April 28, 2006, 10:24:00 am »

The fifth argument can also be a variable, useful in Paint programs with eraser mode...

this one is't mine but it helped me a lot

getkey>G
End

this waits until you press ANY key then continous on, useful for talking in your game

Radical Pi · « **Reply #10 on:** April 28, 2006, 10:54:00 am »

Do you mean Repeat getKey:End? It is useful most of the time.

Another trick I like I used in GQES to boost speed:c1-->

CODE

ec1Repeat (long keypress condition here)
Repeat Ans
(grayscaling code here)
getKey
End
End
Ans->Kc2

ec2The long condition slowed down the loop on every cycle. This way fixes that.

actually if u want better key detection that can be useful, I did that in reuben quest

Radical Pi · « **Reply #12 on:** April 28, 2006, 12:44:00 pm »

Really? ^^
I'm finally learning something...

I have a nice string searching routine I'll post.

*reads Definition of memory errors

uh oh, does recursion really cause a memory leak?

sigh, i hate goto's that the number one problem with my game right now (well maybe number two, laziness comes first

)
but so far it kinda works fine right now
