Legacy GM Cannot assign to "100" - its a constant

[Heretic Game Studios]

Hello GMC Community,

I am getting an error when I compile my game that states:


In Script script6 at line 2 : Cannot assign to "100" - it's a constant

Compile Failed - Please check the Compile window for any additional information

Here is script6:

if place_meeting(x,y,obj_bub)
{
(100 * score_multiplier) += score_total;
}

anyone know this is happening?

That's invalid GML syntax. LHS of a statement is not supposed to be an expression; and 100 * score_multiplier returns a constant value and you can't make changes to it. Swap RHS and LHS:

score_total += 100 * score_multiplier;

You wrote the assignment backwards.

(100 * score_multiplier) += score_total; basically translates to "increase 100*score_multiplier by score_total", which makes no sense.

You should change it to score_total+=(100 * score_multiplier); which means "increase score_total by 100*score_multiplier".

it's
variable = new value...
not
new value = variable

This is like pouring coffee cups into coffee

score_total = (100 * score_multiplier);
you are using this +=
score_total += (100 * score_multiplier);

so make sure the variable was initialised to 0 before adding to it.
