Basic movement-thrust-inertia?
-
in part of my game I want the control to be like the retro asteroids game. I got the rotate left-right working but I am lost on how to do the forward movement, I know it has to do with the rotation direction of the ship and I can read the rotation angle but how to convert that into a movement direction and how to keep moving afterwards. I have read the tutorials and looked at vectoids is that the name? in the programs but that is a different kind of movement and not what I want. how do I do it?
-
@Sgtelite78 try looking into some of the sample projects or there's a video on movement on the fuze youtube
-
Thanks but like I said I tried the tutorials but their movement is not the same as I wish to use. maybe it can be adapted but I dunno how.

Don't need it, working now. used some sin/cos with setspritespeed

Use sin and cos
Ie
New_velocity_x = sin ( ship_angle ) * thrust
New_velocity_y = cos ( ship_angle ) * thrust
Then add together your
Velocity_x =velocity_x + new_velocity_x
Velocity_y =velocity_y +new_velocity_y
Then add to your position
X_pos = x_pos + velocity_x
Y_pos = y_pos + velocity_y
Also don't let the velocity get to high or you'll zip straight off the screen -

Thrust should be small .
I think when I made a similar game I had it accumulate to 10 then divided by 10 so it never got bigger than 1 -
