not sure if this has already been mentioned, but DMA copies are best for main ram to vram copies. main ram to main ram copies do not perform as well with DMA copies.

Well, that explains everything! It must have been a mistake in the example then - thank you for the fast response! I take it that I can still use commas to separate expressions that I want to use together? Like: for(i=0;i<5;i++, foo--){...} Sorry for not checking myself - I'm on mobile so I can't c...

you are not quite right...

for(i=0;i<6;i+2){...}

is not valid

more like this

Code: Select all

for(initialize;condition;evalute after each loop before condition) {
    //do stuff
}

it works like this

Code: Select all

initialize;
while(condition) {
    //do stuff
    evalute after each loop before condition
}

The parameters to the function describe the screen resolution and the region of the screen to print to. In particular the 20, 20 values set the start x and y valu...

your code example does not reflect the question you are asking, so it is a little hard to answer. in the question you asked the variable should change to 7 since you did not indicate that a new local variable was created. In the code example you provided you did create a new local variable. That bei...

You need to read up on "scope" and local variables in C. The { character creates a new scope. Variables created at in a scope go away when the matching } character is reached. These variables are called local variables. I think you will find learning C/C++ by forum posting to be very frustrating. I ...

if they are a static size then you can also make them global.

the stack is 16k on the ds - you have overflowed the stack. your local declarations are too big - you will need to either make the global or dynamically allocate them (malloc or new). both will put the objects in main memory instead of the stack. as a note - I choose to ignore if you move new_anim i...
