2 questions...

[petre]

just tried this editor out today, and i have a couple quick questions that i didnt see answered in the help docs...

1. What is the proper syntax for something like this:

If A and B then X else if A or B then Y else Z

2. If I have an actor moving on a path, is there any way to change the speed it is moving along the path?

thanks in advance.

If A and B then X else if A or B then Y else Z

if (A && B)
{
//code for X
}
else if (A||B)
{
//code for Y
}
else
{
//code for Z
}

2. If I have an actor moving on a path, is there any way to change the speed it is moving along the path?

sadly, no.. the speed cannot be changed in game, and can only be set on the paths creation.

there are other ways to do paths tho, (not using paths), some are complex, depends on your needs. what sort of shaped path are you working on ?

just simple single curve paths, almost like throwing a ball in the air, i want it faster when the path is more straight, and slow down near the center of the curve, then speed up again afterwards.

sounds like you simply want the basic "gravity style" curve ?

like the attached example ??

yeah, that works. thanks.

i got one more question though. if i have an interger variable, how would i convert the number to a string i can display?

the easiest way is to create a text actor then assign the integer to the textNumber variable

eg:
textActor.textNumber=int_variable

more questions!

i want a bullet actor to move directly towards a player actor, not following the player around, just flying on a straight path towards the player initially. i tried using moveto, and it works except the bullet stops when it gets to the spot where the player was when it was fired. i want it to keep going till it goes offscreen. how would i do that? is there a way to just calculate an angle of direction from point a to point b?

and another...is there any way to rotate actors (the animations)?

and now im having a problem...when i make a change to something and then go into game mode, the change that i made isnt there. ive even saved, exited and restarted GE, and it will still have the pre-change game when i go into game mode. why is this?

you can use directional velocity
in create actor of the bullet put in

angle=direction(x, y, player.x, player.y);directional_velocity=3; //put in your target where player is and your own speed

no, theres no way to rotate the animations.......yet....
only manually in a paint program and having pictures of every rotation angle

try my sprite rotation programe to create prerotated sprites.. it's not finished yet, but works ok... so you may need to read through the posts to find out its current limitations.
