angular movement

[157pl]

i have been working on wrighting functions using global code so that i can load them into games. this way i can program faster and still edit the code. i am trying to make a code that moves at a speed that you input and at an angle that you input but i cant think of a code that will make it move at the angle at the right speed. can someone help?

Code: Select all

angle = 180; // Put whatever angle in for 180
directional_velocity = 2; // Put whatever speed for 2

or if you really wanted to make your own function in the global code put:

Code: Select all

// Change angular_movement to whatever name and ang and speed to whatever names. Just make sure you // change them accordingly below
void angular_movement(double ang, double speed)
{
angle = ang;
directional_velocity = speed;
}

Then when you want to use it

Code: Select all

angular_movement(180,2);

This would give you the same result as the first code.

thx i didn't know that those existed.

Jimmy, for some reason angle and directional_velocity aren't working in global code... It's frustrating.

[jimmynewguy]

Code: Select all

void angular_movement(int ang, double speed)
{
angle = ang;
directional_velocity = speed;
}


It seems to work if ang is an integer and speed a double..

Doesn't work for me still.
Placed your code in global code and wrote to actor's draw actor code:

Code: Select all

angular_movement(5, 5);

But it didn't move.

odd. this .ged seems to work but others don't.

EDIT: Doesn't work anymore...?

Nope, doesn't work.

didn't work for me either.
But after trying a few ways, i found that if you initialize the angle or the directional_velocity variables before calling the function angular_movement defined in global code it works.
by adding

Code: Select all

angle=0;

or

Code: Select all

directional_velocity=0;

before the function call, it will work.

attached is a .ged that shows 3 actors
1 actor initializing the angle before the function call (works).
1 actor initializing the directional_velocity before the function call (works).
1 actor just calling the function without initializing any of the variables first(doesn't work).

By the way, the below .ged has defined double for angle and double for speed, it works, it seems to be an initialization problem or maybe how GE optimizes code maybe? (like checking to see if the variables are initialized at all before it even tries to even animate your player? not sure. but hopefully it'll get rid of some frustrations for beginners like myself.
