Game would not run in game maker and it said "cannot use function/script name for a variable,using"motion_add"

Question

this was happening to me as I tried to make an astroids game on game maker. I put in the code motion_add[image_angle, 0.2] and it was working fine then it said

"cannot use function/script name for a variable,using"motion_add"

if you guys could help me I would be grateful thank you.

Hi new GML user! If your question was answered, could you please mark the answer as such? Thanks! — Rob, Jun 05 '19 at 11:22

You are using the motion_add() function. The syntax should be

motion_add(image_angle, 0.2);

when you use the " [ ] " symbols for the arguments, as you did, you are telling Game Maker to look for the data in the "motion_add" array at the coordinates "image_angle" and "0.2". That is not what you want. Also, do not forget the ";" at the end of your line.

hey thanks but I tried running the game again and I it says "error in object obj_spaceship,event up, action 1 at line 1, position 11:assinment operator expected and obj_spaceship is my sprite – new gml user Jun 20 '16 at 14:32
Does your "UP" event contains more than this this line ? (If it's the case, post the full event code please.) And I believe obj_spaceship is more likely to be an object than a sprite. This new error is different, maybe you should ask it in a new question ? – An intern has no name Jun 20 '16 at 14:37
that line is the only code I had for the up event and by ask it a new question do you mean use a different event or code – new gml user Jun 20 '16 at 15:40
Do you have a ; at the end of your line ? – An intern has no name Jun 20 '16 at 15:46
Yes, you need one :) – An intern has no name Jun 20 '16 at 15:53
At the end of the line. – An intern has no name Jun 20 '16 at 16:00
