a2StartLineBatch batchSize

Parameters

batchSize

Boolean
An estimate of how many unfilled shapes will be drawn in this batch.

This command does not return a value.

Description

This command begins an Advanced 2D unfilled shape batch drawing operation. The command works with all unfilled shapes. The batch size is an estimate of how many unfilled shapes are to be drawn. It doesn't matter if it's too big or too small, but the closer it is the more efficient the batch.

Example Code

a = timer()

for x = 1 to 100000
    a2Line rnd(screen width()), rnd(screen height()), rnd(screen width()), rnd(screen height()), rgb(rnd(255), rnd(255), rnd(255))
next x

t1 = timer()-a
a = timer()
a2StartLineBatch 100000

for x = 1 to 100000
    a2Line rnd(screen width()), rnd(screen height()), rnd(screen width()), rnd(screen height()), rgb(rnd(255), rnd(255), rnd(255))
next x

a2EndBatch
t2 = timer()-a
set text opaque
print "No batch:";t1;" milliseconds"
print " Batched:";t2;" milliseconds"
