:P

start with learning how to script

Hi.

It's not done yet, as you might notice.

:P I didn't ask you to tell me I need more help scripting.

..... start by learning the basics... if (playerenters)message Hello;
for example... just learn to do those simple things first then slowly advance... look at scripts on this forum and try finding out what they mean.. look at the npcprogramming.doc in your graal folder... it helps a bit.

Well I won't go on the assumption that you are not a l33t script0r, so instead I will tell you what I did, your math kind of needs to be strong to do this, and I wish I had a scanner so I could upload me notes, I'll try to overview.
If you think about it, on pong, you have 360 degrees, right? Well you can just cut it in half, to 180 degrees and two modes for x and y, so xmode = (0 || 1); ymode = (0 || 1); and each mode has 180 degrees. So like this, you can, using triginometry (sp?) figure out the direction of any object:

NPC Code:



xincrement = (cos(angle/57.3)*speed)-cos(angle/57.3);

yincrement = (sin(angle/57.3)*speed)-sin(angle/57.3);



Because remember circles are also 360 degrees...

where speed it the amount of space you want it to move each increment.

Than to move the actual object (assuming ox, oy is the object's x and y) you could simply do this:

NPC Code:



if (xmode == 0) ox+=abs(xincrement);

else ox-=abs(xincrement);

if (ymode == 0) oy+=abs(yincrement);

else oy-=abs(yincrement);

Than assuming that mx and my is the max x and y, and lx and ly is the least x and y, we can reverse the mode on hits.

NPC Code:



if (ox>=mx) this.xmode=0;

if (ox<=lx) this.xmode=1;

if (oy>=my) this.ymode=0;

if (oy<=ly) this.ymode=1;

Hope that helps.
