在这里,我尝试在GLKVector2Add
值中插入一个值,但错误在此行中缺少预期的表达式。
GLKVector2 self.position = GLKVector2Add({-200.695, 271},{-803.695, 0}); //Error - Expected expression
Try creating " GLKVector2
" variables, setting them and then passing those as arguments in your call to " GLKVector2Add
". It may be that the compiler simply doesn't know what to do with "{-200.695,271}" (a mix of float and integer numbers).
You must add them using GLKVector2Make
.
So, your code will be:
GLKVector2 position = GLKVector2Add(
GLKVector2Make(-200.695, 271),
GLKVector2Make(-803.695, 0));
